SInce upgrading to Firefox 4 none of my web pages will down load unless I am movinh my mouse on the screen. Windows 7 operating system. This is not happening in IE

When I try to refresh the page or navigate to a new page/request pop up, nothing happens until I start to move my mouse and then the page downloads???? This is not happening in Internet Explorer and only started since downloading FF4

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

Just upgraded to firefox 4 and websites are now taking ages to load, there were no problems when I downloaded the upgrade. Is there a fault with the new version of firefox?

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

Ever since I updated my OS, the screen on my Mac will automatically become huge if I keep my mouse on the screen. I can't figure out how to return the screen to a normal size. Any help?

Hold down the 'ctrl' key and scroll backwards on the mouse.
Then go to System Preferences > Universal Access > Seeing. Turn off the Zoom feature.
Similarly in Sys Pref > Mouse uncheck the box for 'Zoom using scroll wheel…'
If it still occurs after that there may be a corrupt .plist file.

Since upgrading to FF6 and now through FF7 web pages need repeated refreshing to load this does not happen with other browsers. I have tried many solutions. None have worked. Any ideas?

Problem began after a Firefox 6 update (i do not remember which one) and has continued through current use of Firefox 7.0.1. Almost all '''web pages load only through repeated refreshing'''. If I do not refresh the web page it will just continue to try to load (as seen by the green rotating ring continually revolving) in a new window with a new tab (as I have set it to do). Nothing stops, nothing crashes. Once the web page completes and opens (after the refreshings) I can close the window click on the bookmark icon or originating link and the web page will load and open quickly (as it should). I have searched for solutions on the Mozilla site and have done many of the possible solutions (deleting history and caches, etc.) Problem seems to be communication in origin (my FF browser talking to web page server). I do not use a proxy. My set up to the internet is: laptop thru Verizon USB modem to internet. Operates as a wireless dial-up with speeds averaging 55 kbs (fast enough for me). I have used this set up for years with no previous trouble. Anyone have similar trouble, ideas or solutions?

Thanks for your reply cor-el. I had never heard of nor seen the pref network.http.max-connections until I read about it in some of the replies in this support forum. People were saying 256 was the old setting and a new setting of 48 would correct my problem. When I followed the instructions to get to - see - and change the setting I discovered that my network.http.max-connections was already set to 48. I never did this. The only way I can think of that this setting was changed is that it happened by an automatic update to my Firefox browser. So, the problem I have was probably happening while this setting was at 48 all along. It is still set at 48 and I am still having the same problem. I will try as you suggest and set it to 30 and see what happens. I'll let you know the results. That's again for your response.

After upgrading to Firefox 4.0.1, it no longer will open external links - anything from emails, IMs, databases won't open - how can I fix this?

No links from external programs will open - this is usually kind of ok since I can cut and paste, but some links from databases don't provide copy-able links, meaning I cannot access information via Firefox.

Hi BladedxRayne,
You should look at the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved].
Hopefully this helps!

I have not been able to open any spreadsheets Microsoft Excel or OpenDocument Calc since upgrading to Firefox 4.0 and my web-based email services has reverted to an archaic version. Why have these issues developed since I made no other changes or updates?

I have included everything I know about it the above question. The crazy thing is that it has affected the ability to open any of my spreadsheets even though that should have nothing to do with my browser. I made no other changes to my computer and there have been no automatic updates going on from either Microsoft or OpenDocument at that time or even since.

Try with Flash clean install

For some reason if I click a link that needs to open in a new window, the new window is blank. This just started happening when firefox updated itself last time

Ever since firefox automatically updated itself, I am not able to open websites in new windows - meaning that if I am on a website and you click a link on it that opens in a new window, that new window is blank. It used to work perfectly. I even checked my foxit reader and that it working well

Hello Angelika.
I should bring your attention to the fact that your user agent says you're using Firefox 3.6, not 3.0. I will remind you that Firefox 3.0 has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems.
As for your problem, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

What is the latest version that will work on my "vintage" Powerbook G4 Mac Laptop running the 10.5.8 operating system and where is that download on the Firefox undating site?

The latest version of Firefox is not compatible with my Laptop, and I could not find which of the latest versions I can use.
I was trying to upload the latest version and received an incompatibility message.

A group of Mac users have created their own Community Build from the "Firefox 4+" versions.

I zoom in on page, but if go to another page then return to original page, the zoom has been reset. This did not happen with Firefox 3.6.1., the zoom level would remain.

This only happens with my laptop running windows 7. No problem with my desktop running windows vista.

I was running Firefox in Private Browsing mode. I quit PB and now the zoom feature is working as it should. Problem solved...Thanks.

Since the update loaded on my computer my web pages will not load and i get invalid url message

Ever since firefox updated to 17, my web pages will not load. When I type in the search bar and hit the enter button, the address switches to https and i get a message stating that my page is an invalid url and the following message
Reference #9.1db78443.1354339468.3c70717c
I have cleared my histories and cookies and restarted my computer but cant get it to work.
I can type in www.google and go directly to the google page and then gain access to my pages, just not through the firefox address bar.

Since upgrading to Firefox 4 every time I open or refresh a page everything freezes and I have to wait a minute or so for it to respond again. I'm also having problems with uploading to Photobucket and watching things via Youtube since the upgrade.

Since upgrading to Firefox 4.0 a couple of days ago, every time I open or reload a page the whole browser freezes. At first I thought it might be down to compatibilty issues with other programmes open at the time, but as the problem has persisted when those programmes aren't open I'm starting to think it's the browser itself and it's getting extremely frustrating having everything freeze every time I want to change a page.
My other problem is twofold: with Youtube nothing plays at all because the toolbar with the play/pause option simply isn't there and I am unable to access the upload function on Photobucket because likewise it won't appear. I'm assuming this has something to do with Flash but have no idea how to fix it.
I've tried

hello, often such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions. please remove all program rules for firefox from your firewall and let it detect the new version of the browser again.

I can no longer attach files in Yahoo mail since upgrading to FireFox 4.0.1. I click the "attach" button and nothing happens - no file list to select from appears; nothing.

Since upgrading to Firefox 4.0.1 the "attach files" function in my Yahoo Mail account no longer functions. When I click the "attach files" button nothing happens - nothing. No file selection box opens, no error message appears, no pinwheel of death, nothing.
The "attach files" button is no longer 'hot' in FF 4.0.1 either = the "little hand" icon does not appear when I scroll over it. Other action buttons are still 'hot' ("attachments", "emoticons", "format", "hide bcc"etc.) - just not the "attach files" button.
The Yahoo Mail "attach files" function still works when I use my Safari browser, however. So, it appears to be a FF4.0.1 issue.

Since upgrading to Firefox 27.0 some webpages will not load when I click on them. It gives me a message saying that Firefox can't find the server.

Since upgrading to Firefox 27.0 some webpages will not load when I click on them. It gives me a message saying that Firefox can't find the server. I have to click the link several time before it will load and sometimes when they do load it does not show the page right. It is like the HTML is messed up or something. I have tried everything I can think of. I started in safe mode, still did it., I removed add-ons, still did it., I reset Firefox and still did it., I completely uninstalled Firefox and re-installed Firefox and it still does it. I have tried Malware Bytes Anti-Malware scans and Avast boot-time scans and found no malware or viruses. I have found that those websites open the first time with no problems on my IE9 and they used to do so in Firefox 26.0. I'm at my wit's end. The website links are in my bookmarks and are used all the time so they are trusted and my avast is set to allow them. They range from news websites to gun websites and everything I have read says that Mozilla does not filter those unless something has changed recently.

Try this as a first step; 
Clear the Cache '''''Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"''''' 
and 
Remove Cookies '''''Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"''''' 
If there is still a problem,
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]'''''
While you are in safe mode;
'''''Firefox Options > Advanced > General'''''. Look for and turn off '''Use Hardware Acceleration'''.

What I would call "body" copy is appearing in an unreadable script font on web pages and in emails since upgrading to Firefox 6.0, what can I do to resolve this?

Since upgrading to Firefox 6.0, some copy is appearing in a script font that is really difficult to read. I first noticed it in the body of an email I received, but then saw it on some web sites I was visiting. It also appears when I am typing.
I am on a Mac.

Also, here is what I've done so far to try and troubleshoot it...
I checked other browsers on my computer and it's not happening, I went through and checked for corrupt fonts on my computer, I double checked my font settings in Firefox prefs, I did a google search and attempted all the things I saw listed as potential fixes and nothing is working.
