After startup Firefox only visible maximized

Hi,
Problem 1.
After starting up Firefox, there is for only one second a very small window top left named Firefox. After that it disappears and Firefox can only be viewed maximized.
This is very annoying on 21" screen.
Problem 2.
For some time now I have this "overlay" problem.
When starting up Firefox right after starting up Outlook Express, the two windows seem to sort of "melt" together and are difficult to seperate.
I sincerely hope you can help me out.
Thanks a lot in advance and best regards,
Lody J. Claessen

Try to disable hardware acceleration in Firefox.

When a allowed popup window opens, it is maximized. Before it was the size it was supposed to be but after updating Firefox, everything is maximized.

Popup windows are all maximized. This was not the case before updating Firefox.

After startup firefox will not open immediately sometimes must reboot laptop ??

after start-up I double click on the desktop icon or right click to open and FF will not open. I then must reboot the laptop and it usually opens. It seems to reopen ok later after closing the browser during the day. I had a box appear on opening for awhile that showed some upgrades for some apps (that I always declined) and then it went away after while. Sometimes when I go to open the box appears very briefly and as just a border of the box and then disappears. Could that be the reason for the hangup? Any input would be helpful. Should I maybe just reload the latest upgrade. thanks ahead of time helpful people. :o))

Try a clean reinstall.
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 7.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
* Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Windows 7 home premium pc keeps powering down after startup The only thing I have noticed different is the heat sink fan RPMS rev quicker and seem to stay reved for longer periods. The COMPONENTS ARE DUST FREE. Components do not feel warm to the touch. Ventalation Is over done. The pc will no longer run long enough to do a lot of testing. I will be honest I do not know much, so lets change testing to trial and error.

Firefox downloads like crazy after startup (hundreds of megs)

After starting up firefox it often immediately starts to download hundreds of megs at max speed for no apparent reason, clogging my network.
I've got a lot of tabs open, some youtube too, but after startup those aren't loaded yet, they only load after being clicked on, so they can't be the culprit.
I'm using ff 22.0 on linux. My addons:
adblock plus
download helper
downthemall
firegestures
flashblock
flashgot
noscript
reloadevery
tab auto reload
tabgroups manager

Am I the only one getting calls from 253-802-0308 about malicious file downloads after updating FIREFOX?

After updating Firefox I start getting calls from 253-802-0308 (International Telcom in Auburn Washington, found using 411.com). The report that they are getting messages that my Windows PC is reporting the downloading of malicious files. I don't think that there is a connection with Mozilla but it only started after I ran the last 2 or 3 updates to Firefox. Searches on Google and other search engines don't show logical connections to the phone calls and the problem being reported to me. None of my anti-virus programs, Ccleaner, DEFENDER & AVG pickup and malicious files. I'm curious about who they may be because when I question them during the calls they end up hanging up on me. Just wondering if similar problems are being reported.

That is a reported scammer set-up. Read some of the following from actual phone customers. It is not related to your Firefox updates. I have gotten a few of these types of calls on my '''''unlisted '''''home phone number over the past several years. They use a dialer, usually automatic and sequential number dialing. Get a loud whistle to blow into the phone mouth piece or one of those loud air horns from the hardware/sporting good store; this kind of trash deserves broken ear drums.

Firefox only works after I re-boot my computer

I just got a new computer last week. It is running Windows 8 - 64 bit. I installed Firefox, used it for a week, set up my bookmarks, etc. and it worked fine. The other day when I logged in and opened Firefox, I couldn't click on anything - nothing would happen - it was like it was frozen. I went into Internet Explorer and also into Google Chrome and they both worked fine - I could click on things and it would do what it was supposed to do. So, I re-booted my computer and then Firefox worked fine. Same thing the next day, Firefox only worked after I re-booted my computer...and also today, same thing. Why is it frozen when I first go into it, but if I re-boot the whole computer, it works? Has me baffled. Any help would be appreciated, because it is my favorite browser. But if this keeps up, I won't be using it anymore. Thank you!
I have my home page set to Yahoo, so that's where it goes when I open it. When I get there, I can't click on my e-mail, nothing in the toolbar, it's totally frozen.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
*In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
:[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

After closing Firefox to use IE8 or any other program (like InterVideo to watch a DVD), everything is very choppy and slow. I have to go into Taskbar, Processes, and close firefox.exe manually (which is using up all the memory/CPU and should have closed before). Then, and only then, does everything behave normally. What is going on and what am I doing wrong or missing??

'''[[Firefox hangs]]'''
'''[http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit Firefox hangs at exit (Mozillazine article)]'''
'''[[Firefox is already running but is not responding]]'''
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode is a diagnostic mode that disables extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to close and restart Firefox after each change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Dear Firefox:
I am not amused with the pac-man music. I spent the entire trying to find a virus on my computer. I might have tolerated this as an April Fool's joke, but this "celebration" was completely unnecessary!
And to others trying to fix the problem ... I just uninstalled Cool Previews and that did the trick. No more bat-shit-crazy pac-man music.

Firefox hangs immediately after startup and "awakens" after X seconds

After launching Firefox either click and type in the search box (using google) OR click the favorites icon and attempt to open a favorites folder. Firefox will stop responding to clicks or types. After 5 to 30 seconds, it will awaken and respond normally. Version 3.6.9. This began following the last two or 3 Firefox updates.

After updating Firefox sites are only displayed in text. How can this be solved OR changed back to the old version?

Startpage is normal but after connecting further only text is displayed

I also forgot to note that this problem also persists with the new iBooks application. I cannot get past the 'Get Started' screen or access the iBooks Store. Again, all top bar menus are unresponsive.

Applications take a lonnnnng time to open after startup

I'm not sure if this is a problem or just the way the Mac works. Either way I'd love an explanation if someone knows.
After I start up or restart my Mac, it boots just fine, not too slow or anything. Once it looks like I should be ready to open up applications and get going (i.e. external HD is booted, dock is all good to go), though, it seems to take a VERY long time for them to open. If I open up Firefox, it takes at least a minute to open and load my home page, whereas once this initial slow period is over, it takes only seconds.
I didn't notice this as much with my PPC iMac but it's very obvious with the Intel one. As I said, after the initial slow period is over, everything works fine. Is this working the way it's supposed to? Thanks.

Does this happen to you with all applications?
Yes. It happens with any application I open during the "slow minutes" after I boot up. Entourage, despite working under Rosetta, normally opens almost as quickly as, for example, iTunes. But even iTunes takes forever during this period.
Also, how much RAM does your iMac have?
2GB.
In my MacBook, applications open almost instantly.
Again, this is just in the couple of minutes after startup. Ordinarily my applications open almost instantly as well. I'm just trying to figure out what's slowing my computer down so badly just after it boots up. Thanks for your reply!

Firefox has suddenly gone wrong. I was successfully running both Firefox and Internet Explorer 8 on Windows 7. I auto-accept upgrades including the most recent Firefox upgrade and the suggested upgrade to Adobe Flash 10.1. But after this, Firefox stopped

Firefox has suddenly gone wrong. I was successfully running both Firefox and Internet Explorer 8 on Windows 7. My laptop is new and has plenty of RAM and HDD. I auto-accept upgrades including the most recent Firefox upgrade and the suggested upgrade to Adobe Flash 10.1. But after this, Firefox stopped working and does not work when I re-load Firefox 3.6. Also IE8 now works very slowly and does not locate major websites like Microsoft without a 'can't find the website message' and having to pressing Return a second time. When I do get to the Mozilla website and click on the button to try to download Firefox 3.6.6, I get this message "Oops! Internet Explorer could not find mozilla3.snt.utwente.nl". Can you help with what has gone wrong? As it stands, I can't use Firefox at all. Note: because Firefox did not work after the upgrade, I've downloaded the IE8 version of the Adobe Flash 10.1. What I really want is to be able to use both Firefox and IE8. But is this possible if they use different versions of Adobe Flash?

I have been having the same problem as the original poster. After upgrading to Ffx 3.6.6, the program asks you to upgrade to Flash Player Plugin 10.1. I download and installed 10.1 only to find videos weren't loading.
In my case, the problem is the previous installation of Flash Player (9.0.47) was somehow messing things up. To fix this, because I already had Flash plugin 10.1 installed I had to uninstall 10.1 using the uninstaller from adobe and then manually remove any files related the old flash player plugin 9.0.47
Here is a run-down of my process:
0. To check if you have a previous installation of the Flash Plugin lurking around, in Firefox go to Tools -> Add-ons -> Plugins (tab). At this point you may seen both Flash plugins.
1. Proceed to uninstall Flash Plugin 10.1. Adobe provides an uninstaller here: http://kb2.adobe.com/cps/141/tn_14157.html
( you have to make sure you have nothing running when you execute the installer).
2. On my Mac (sorry I don't know what it is in Windows) I searched the hard drive for any files/folders with "Shockwave". I found a folder called "Shockwave 10". It wasn't removed by Adobe's uninstaller. For safety I deleted it and then emptied the trash.
3. I then went to My HD -> Library -> Internet Plugins.
Remove the file and folder named "Flash player.old"
4. Restarted; ran the Adobe Flash Player 10.1 installer. Restarted again.
5. Opened up ffx and double checked the plugins list (see step 1). Version 10.1 is installed and available. Went to problem sites to test it out and Success!
Hope this helps.

When I open and close firefox about 3 times, I get the blue screen of death. Why? Also Firefox only opens every second time, and I have to close it manually to fix the problem. How can I avoid this?

I have to close the firefox from my task list. Before I do that I can't open any web browser. This is really annoying, and I have had this problem only after using Firefox 4.
