Firefox on Windows 8.1 is over magnified causing rendering issues?

Left in 100% view state pages are rendered far to big with text overlarge and photographs beginning to blur through pixellation. When compared to Google Chrome and IE on 100% there is a vast difference between these 2 and Firefox. To correct this issue I have to put the Firefox display to 80% view to get the same effect as I would on Chrome and IE on 100%. Surely this is not was intended has there been some mistake? I am using Windows 8.1 as platform
This issue although correctable is still a bit annoying having to constantly alter display just so that Firefox has roughly the same look as Chrome and IE. It is annoying because I am a website developer myself so would expect some consistency when developing sites for Chrome and Firefox etc.

Cor-el
thanks for the reply but it is only partially helpful. I followed some instructions in the about:config and found layout cssdevpixels to be -1 valua which I changed. improved some of the text appearance improved but the zoom is still over 100% as compared with other browsers.Going down a route to get add- ons to default the zoom seems a bit too much work really. However what concerns me more is that most users would expect to download Firefox in a useable state or would just use what they got on the download and hence not look to improve or customize what they recieved as a download. Taking your advice is not for the faint hearted as most would fear messing around with settings like these in this way. Therefore people looking a web pages on Firefox may get the wrong impression of a website thinking photos are blurred because of a fault by the website designer or photographer and not looking at the root cause which is actually poor rendering at 100% view on the browser. I only knew because i made the sites that I was viewing so i knew something was amiss. This could put potential customers off what they are seeing especially when its on sites that rely on the quality of the images on the page. This is why i am questioning if this is actually a design fault and not a customization issue. People usingFfirefox are not necessarily going to realize they need to change the zoom to see the website page correctly nor are they going to seek complicated solutions to customize the browser to display correctly. As a web designer it is not possible to put in a set of different photographs to display according to which browser is being used to view the webpage so this is why it is necessary to have everything as standardized as possible this is why i am so concerned about this issue which I seem to be getting with Firefox current version. Really there should not be this variation between different browsers.

Two Fx 4 windows open at the same time causes usability issues

When I load two instances of Firefox, I get multiple issues with the second instance usability, display, and hot keys.
The issues are as follows:
# Menubar/Toolbar appear differently
# Back/Forward buttons do not work
# F-Keys no longer Function
# Favicons show old, cached icons
Please see screen grab of my two monitors with two instances of Fx 4 open, but the I played with my toolbar settings to get it to look somewhat ok.

This is what happens when I open a second window, and do not mess with the toolbars:

This issue was not happening with Fx 3.x.x.
I am using a custom Persona, but I have changed the Persona a few times and I still get the same result.
I've removed all incompatible extensions and upgraded all the ones that needed upgrading.
Not sure what the issue is here, but would love to troubleshoot it down if possible. Please let me know if any other info is required!
Cheers

Exact same issue here. Also, the add-on manger will not launch.
I thought it might be an add-on causing these issues, but only one out of my ten or so addons work in FF4, and I disabled it with no success.
This is a huge issue for me. I attempted to uninstall FF4 and go back to FF3 but I can't find an install file for FF3.

WebGL causing Rendering issues since firefox 28/29

For a long time the whole of firefox used to flicker all time, and sometimes it stays black till I resize the window. A lof Google search lead me to a solution (disabling hardware acceleration/many other things did not work) to disable WebGL in about:config and that solved my problem to a great extend. Now, the same issue is up in simulator, and as far as I searched, I am not able to disable it in Simulator. Is there any solution to fix this in Firefox (and hence in Simulator)? Sometimes the screen just freezes, though the pages are loaded in background.
I'm running Firefox 34 in Windows 8.1, on Lenovo B460e.

''cor-el [[#answer-676292|said]]''
<blockquote>
As you can see on the troubleshooting information page there are issues with your graphics display and the driver.
You can try to disable OMTC and leave hardware acceleration in Firefox enabled.
*about:config page: layers.offmainthreadcomposition.enabled = false
You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

Thank you! That fixes the problem in Firefox, but Simulator still behaves weird! Any solutions?

Since I installed Firefox 3.6.3, every time I open Google Notifier, two Firefox browser windows open.

I am running Firefox 3.6.3 on my Mac G5 and my MacBook.
Since I installed Firefox 3.6.3, everytime I open Google Notifier, two Firefox browser windows open. This happens on both of my computers.
This never used to happen before, in the earlier versions.
How do I make it so that only one browser window opens?

I got this all screwed up too.
hmm.. where to start?
3.6 and 4.0 beta - really aren't intended to play well together.
As has been mentioned above, they tend to write over each other.
I managed to get both 3.6.15 and 4.0 beta 12 on the same machine.
But, I had to do it several times.
I got lucky by deleting everything Mozilla, then installing 4.0b12, then 3.6.15 - while making sure that each installed into a separate folder.
I also took care to copy out a couple of BookMark BackUp files - just in case.
My old 3.6# had become so bloated - and, Unstable - for Me, it was time.
The bookmarks were all that I was still interested in.
All the Plugins, Themes, AddOns, etc... had slowed the app to a crawl.
So, I did as complete a wipe of Mozilla bloat code that I could, including profiles.
I then did some registry cleaning.
Then I installed 4.0b12 and 3.6.15.
I can't open them both at the same time.
If I open 3.6.15 first, then open 4.0b12 - the beta comes up as 3.6.15.
If I open 4.0b12 first, then open 3.6.15 - the 3.6 comes up as the beta.
This has a lot to do with both apps sharing the same default profile.
I hope to drop down to one app in the near future.
So, cobbling multiple profiles in order to diddle side by side apps - isn't worth it at this stage.
For me, I can't open FF 4.0b12 when my virus protection is running. PCTools doesn't like some thing about the way FF4.0 wants to phone home when it opens.
So, I can't commit to the 4.0b12, yet.
3.6.15 was crashing on open too - until I uninstalled the feedback addon. - go figure -.
Also, I can't get the 4.0b12 to start in safe-mode with the PCTools antivirus running.
At the rater they are going, I don't see 3.6.# going away any time soon.

Unexpected performance of Firefox in Windows 7, namely minimize/maximize/close buttons not working and unable to move/resize window.

I have been using FF for a while now. My main computer was WinXP-32, though I recently bought a new laptop with Win7-64 installed. This problem was never experienced on my WinXP machine.
Brief description of problem:
After a time of having FF up and running, the minimize/maximize/restore/close buttons in the top-right no longer work as expected and, if not maximised, I cannot move the window around my desktop nor resize the browser window. When clicked, the buttons will
rapidly flash on and off continuously without appearing to perform any noticeable function other than temporarily hogging CPU cycles. I've found that clicking (sometimes double clicking) in the main browser window then mousing over the buttons again seems
to stop them flashing, though does nothing else.
To minimize/maximize/restore/move/close the window(s), I have to right-click on the relevant tab in my taskbar and pick the desired option. Occasionally, however, even this doesn't work and the right-click menu will disappear as soon as I move the mouse
over it after right-clicking. 'Show desktop' is a temporary fix for minimising windows and 'ALT + F4' or 'CTRL + W' for closing windows or tabs. This isn't satisfactory and to move or resize a window, I have to close the window in question (sometimes all other
windows too), reopen it and do what I need to do, though sometimes even this is only a very short fix. If I have to close all the windows, FF will sometimes keep running for a while afterwards, even though no windows are actually open - simply ending the process
via the windows task manager will fix this though is only a work-around, not a fix.
One thing I have noticed is that if I manage to move the browser window (when not maximised), for a short period afterwards I can often resize the window successfully. This is more likely to occur if the browser window is not flush with the edge of my screen
once moved.
I've tried to include as much information as I can - most of which was determined after several minutes/hours of playing around with different scenarios, trying to manually reproduce particular problems or simply through sheer luck of happening to click
in the right place at the right time! I hope there is a reasonably fix for this at some point in the not-too-distant future.
I noticed in some of the threads at another site where people have voiced problems similar to mine, that a link to 'ObjectDock' was discovered in some cases. I do have 'ObjectDock 1.90 Plus' installed on my machine and use it in many ways and so decided
to see if I could find a connection between the two. I have uninstalled, tested, and reinstalled both programs in a multitude of ways, though could find no conclusive correlation between having both bits of software running or installed at the same time and
the problems I am experiencing. In my case, at least, this does not appear to be an answer.
Also, in another thread on this site, someone suggested there might be a link with AVG Anti-Virus Free (I have version 9.0.819) though I've tried uninstalling it and its various add-ons in several different combinations, with no noticeable improvement.
Sorry for such a long question... If you need to know anything more, just let me know!

Hi Kossa,
You can also check if the issue occurs in
Clean Boot. If the issue disappears in the Clean Boot environment, you can continue to narrow down which entry is causing the issue.
Besides, uninstall it and re-download
a fresh copy of FireFox to check the result. If the issue still exists, create a new user account to see if it occurs.
If the issue persists, you can contact Mozilla Support directly and use Internet Explorer (IE) during the time.

When I open a second Firefox browser window, the URL address window, instead of showing the URL, says "Go to a Web Site;" also, and more importantly, the "back" button is greyed out. This is a new problem, and the first Firefox window I open works fine.

After I open the first Firefox browser window, any additional window I open does not open my homepage, but opens a blank page with "New Tab" showing on the tab. An orange "Firefox" tab with a drop down arrow shows at the upper left hand corner of the screen. All of the options (File, Edit, etc.) are greyed out, however they will work if you move your cursor over them.
The URL address window says "Go to a Web Site". After I've gone to a website, the back button remains greyed out and I am not able to go back to a previous page. My RoboForm and Netcraft toolbars only show up in an abbreviate form. The add-on bar doesn't show up at all.
Again, this is a recent problem, and only happens after I've opened one browser window (which works fine) and then open additional browser windows (as few as one additional).

I had this same problem. Seems to be caused by the web developer tool bar FF extension (this started happening after a recent update to that extension). After disabling it, my FF is back to normal :)

High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-(

Get Windows Temporary Profile on restart after updating Firefox on Windows 7

This happened a month ago when going from 15 to 15.0.1 also. And again now when upgrading to 16.0.1.
I have no idea how it fixed itself last time as I tried everything over the course of multiple days last time (many reboots, restarts, etc.). Ended up creating two additional accounts, just had the one originally, in order to copy all my files and start over last time. Then, seemingly at random, the original profile worked in which I noticed two instances of FF, 15 and 15.0.1, in the control panel so tried re-installing FF 15.0.1, even though the manifest listed it as successful, which fixed it.
Now the exact thing is happening again after upgrading to 16.0.1. It was a successful install, verified before rebooting via update history and closing FF and opening a couple of times, and it then only listing 16.0.1 in the control panel. But, on the first restart, Windows 7 goes into temporary profile mode again. I tried creating a second account again in hopes the first would magically work again, as I have no idea how I got back into the original profile the last time it happened, to no avail.
Can anyone help? I hate to give up on FF as I've been using it exclusively for years but I don't want to go through this a third time.
Also, what can I do to get back into my original profile so that I don't have to start from scratch yet again copying my files and recreating all my settings?

Update.
After many logoffs, restarts and switching user from the temporary profile and the second user account, it randomly let me back in to my original profile again.
I literally did nothing to allow me access to it other than many of those attempts.
As soon as I was in my original account again, I immediately went to the control panel -> uninstall a program and verified, same as last time, that it listed two instances of FF (recall that it did NOT after I upgraded before the first restart and getting the temp profile). I opened up FF, 16.0.1, and downloaded it again from http://www.mozilla.org/products/download.html?product=firefox-16.0.1&os=win&lang=en-US
Installed that, even though it was already successfully installed according to FF. And just like last time, that removed the earlier instance of FF, 15.0.1, and all is back to normal. Verified by restarting multiple times and no longer getting a temp profile (exactly like last time which lasted for about three weeks until the 16.0.1 upgrade).
This never happened until 15.0.1 and now 2 for 2 with 16.0.1. What is going on that would yield a successful upgrade yet on Windows 7 first restart after is causing it to kick to a temporary profile (yet also fixed, if one gets lucky enough to get back their profile, re-installing it over fixes it until the next upgrade?)? Some file not being created/deleted on reboot that is confusing Windows when trying to load the user profile?
I'm willing to copy over my W7 user profile to a flash drive and Fedex it to the FF team if one can fix this. It is the most basic software setup that I can't imagine others aren't experiencing the same issues.

Firefox 5 window stays on top of other windows

On an old Windows XP SP3 system, in the last few days, Firefox 5 window always stays on top of other windows that I may have open. In order to see the other windows (applications) that I have open, I must minimize Firefox 5. In the past, clicking on the title bar of any other window/application, would bring it to the front, but that does not happen now; clicking on a title bar other than Firefox 5 does focus the other title bar and Firefox 5 title bar does change to the non-focused color, but the other window/application does not come to the front (over Firefox 5).
This has just occurred in the last few days. I have added no new programs and no new extensions to Firefox, but several Firefox add-ons have been updated.
How can I get Firefox 5 to not dominate my desktop?

In the past, clicking on the title bar of any other window/application, would bring it to the front, but that does not happen now; clicking on a title bar other than Firefox 5 does focus the other title bar and Firefox 5 title bar does change to the non-focused color, but the other window/application does not come to the front (over Firefox 5).
This has just occurred in the last few days. I have added no new programs and no new extensions to Firefox, but several Firefox add-ons have been updated.
How can I get Firefox 5 to not dominate my desktop?

After updating to Firefox 24, Windows 7 64-bit breaks on reboot. The network icon in the taskbar not ready (blue circle stopped).

After updating Firefox 24, Windows 7 breaks after reboot. The network icon in the taskbar is not ready (blue circle over wifi network icon). But I can't do much. I can not open the network and sharing center (never opens). Even the task manager will hang when I click to show processes from all users. I have to do a system restore to have a functioning network again. I never even launched Firefox.

Thank you for your response. I agree that the steps you list should have a working Firefox 24, but it did not work. I don't know what other information to gather to help assist in diagnosing the cause. If I restored to a good state and then (re)installed Firefox 24 and reboot, I have a problem.
Thank you.

Strange bug in Flashplayer for Firefox on Windows

Hello All,
First, I'm not sure that it's the right forum, as suspect the
bug to be in the flash player implementation more than in my code,
but here goes:
I have a simple .flv movie player. On mouse move (Over the
stage), an interface appears on top of the FLV playback component,
allowing the user to pause the movie. After a short while of no
movement, the interface disappears again.
This works well. The interface is not in the way and only
there when needed. The only problem is that I'm experiencing some
trouble with flashplayer for firefox on Windows. It works as
advertised in IE, 6+7 and Firefox/safari on Mac. The error
reproduces over several computers, so it's not a buggy
installation.
What happens, is that the FLVPlayback component pauses when
the mouse doesn't move. This is of course a problem because of the
40% black overlay that is part of the interface. So you can only
see the movie if you keep you mouse moving within the player, and
is able to distract from the interface overlay.
I implement the mouse handling as shown.
That's all there is to it. The show and hide functions do
just that. Make a _root.onEnterFrame and uses that to show or hide
the interface like shown.
Nothing in there has anything to do with stopping the
playback. I'm showing a button, that's all. Not clicking it.
The error only occurs in Firefox on Windows.
I suspect it's something to with Event handling, when leaving
the Stage area.
Is done in Flash 8 on MacOSX
Any ideas?
Best regards,
Michael

Firstly there appears to be a bug in the Kerberos libraries where it does not look at the local cache on XP. Try with -Dos.name="Windows 2000". This should trick the java libraries into thinking it's on W2K and look at the LSA cache. There appears to be other issues here but still trying to investigate further.
Secondly you haven't specified a CallBackHandler yet you have DoNotPrompt =false. Thus Kerberos will try to ask for the username and password (since it doesn't talk to LSA) yes none is defined in your call to LoginContext.

Firefox main window goes black and all tools disappear.

Occasionally the Firefox main window will go black and all tools disappear.
It ends up with a black window, a blue frame, and the three buttons in the top right corner (minimize, maximize and close). If any audio (or video) is playing, the sound continues. If I click the X at top right to close it, it closes and when I restart it everything is ok. See the screenshot below.
This only happens once a day or so. I have no way of predicting it other than I'm usually scrolling down the page when it happens. It has happened in safe mode.
I'm using the most recent Firefox, 33.0.2, on Win 8.1 on an i5 system with 8G RAM.

Try to disable OMTC and leave hardware acceleration in Firefox enabled.
*layers.offmainthreadcomposition.enabled = false
You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.
*http://kb.mozillazine.org/about:config
You can try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.

How can I remove livesearch from the Mozilla Firefox browser window?

Somehow I got the live-search malware embedded into the Firefox browser window. I have tried to remove it using SuperAntiSpyware, Spybot-S7D, and Malwarebyte. Plus ran AVG. Did all four of these several times. But I still have livesearch.
How do I get rid of it? Will uninstalling Firefox and the reinstalling it work. If I uninstall Firefox and reinstalling it, will I loos all my bookmarks?
Please Help!
Thanks,
Naturewoman

Generally speaking, uninstalling and reinstalling Firefox doesn't solve most problems unless you remove all your personal settings, which I definitely do NOT recommend.
These kinds of infiltrations can take some effort to remove. To make it easier, Firefox now had a "reset" feature which preserves your bookmarks but strips away custom settings and extensions, which are the source of most problems.
You could try manually removing the "Printing Helper" extension and resetting your search settings first. If these don't help, then try the reset.
orange Firefox button (or Tools menu) > Add-ons > Extensions category
Then run the Search Reset extension from here:
https://addons.mozilla.org/en-us/firefox/addon/searchreset/

Any luck?

Using Firefox 4 & Windows 7. Everytime I start Firefox from a shortcut to a website it comes up with the following error 'there was a problem sending the command to the program'. The requested website does load after this. with no problems.

If a shortcut is used while Firefox is already open the error does not occur.

As reported in earlier replies, the annoyance disappeared after I upgraded to Roboform 7.5.6, from 7.5.4.

I have downloaded mozilla firefox a number of times. Over a few days it tells me that the firefox is no longer on my computer. I never delete it. Please help. I do use CCLEANER.

You are unfortunately out of luck with an Intel Mac and OS X 10.4.11 
Best would be to update to OS X 10.5 or later if you want to use Firefox 4 and later versions (current is 8.0). 
There is a Firefox 8 compatible third-party version TenFourFox from www.floodgap.com for a PowerPC Mac, but no alternative for an Intel Mac with Mac OS X 10.4.
Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:

Firefox on Windows 8.1 is over magnified causing rendering issues?
