Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

As soon as Firefox opens, it starts increasing memory usage until it maxes out, and it won't actually close unless I end the process in the task manager.

Even if I'm not doing anything, no matter how few tabs I have open, Firefox will slowly increase in memory (RAM) usage until it's using nearly 100% of my computer's RAM, and everything basically freezes. Even when I close the window, the process continues to run, and I have to end the process in the task manager in order to get it to stop using RAM. I've tried disabling all my add-ons, and that does not help.

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

When I enter the website, Firefox stops responding and I have to end the process from the Task Manager. How do I solve this problem?

I am running Firefox 4.0 beta 7 on Windows XP Tablet Edition OS. When I enter this site using Firefox, the browser stops responding and I have to end the process using Task Manager. However, when I open it with other browsers such as IE8, I am able to view the site as per normal. This only happened when I updated my browser to Beta 7 and I did not have such problems in the previous betas.

There is [[Flash]] content on that page.
Do you have a problem with Flash on other websites?
Create a new profile as a test to check if your current profile is causing the problems.
See [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. (continued)

Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. The only way I have to fix it is to change some kind of compability settings or try and access it in a new way, and every time it crashes/closed/computer blue screens that setting will no longer work.
That is a short term solution, but eventually I'll run out of ways to access firefox successfully. I've tried many solutions, and some worked, but only once. I have yet to find a permanent solution for this problem.

First please update your plugins to make sure you are up to date. Shockwave Flash player has a newer version 16. In order to better manage the memory that Firefox uses please see these troubleshooting steps: [https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram Firefox Uses too much RAM]

Firefox does not close in the normal fashion. I have to go to Task Manager and end the process

I am operating on a Windows XP OS. I have been a FireFox user for several years. I am using version 3.6.13 Several months ago I noticed that if I closed FireFox I could not open it again. I got a message box stating that FireFox was still running. And, I fact, Task Manager did show that it was still active. I had to end the process there, before I could open FireFox again. It will remain active in the background and the CPU will be maxed out, thus creating problems for other programs. How can I remedy this problem? btw, I have trouble opening IE now.

Firefox begins to start but then stops before loading any screen. Profile manager/safe mode appear then disappear. Task manager shows programs briefly in CPU then they disappear. Uninstall & reload makes no difference. Any ideas please ?

When we clicked as usual on the firefox icon the egg-timer started then went off. Nothing started up.
Checking the Task Manager showed firefox.exe briefly using the CPU then it dropped off the list.
We tried to uninstall and reload from the mozilla site (http://www.mozilla-europe.org/en/firefox/). Installation seemed to work ok, but the same problem recurred when we tried to start firefox.
Did this again, this time removing bookmarks, etc. same result.
Tried to use the profile manager - the screen came up but disappeared before we could use it.
Same thing happened when we tried to start in safe mode - screen briefly appeared but then disappeared.
Tried googling in IE to solve the problem but nothing seems to apply.
Have run all security checks but no apparent bugs or problems.
Have had to abandon firefox and use another browser. How do we get it back please ?

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, 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.

Firefox already running, profile missing or inaccessible, cannot kill in task manager

For reference, this is on windows 8
In the past I've (very rarely) had the "firefox is already running" error and was able to fix it by ending the process in task manager. I updated to firefox 36 the other day. Since then, firefox will run perfectly normally for a while, but after some time (varies from minutes to hours) I can no longer load new pages. The loading wheel just keeps spinning.
Once this has happened, if I quit firefox and try to open it again, it will give me "firefox already running" followed by "profile missing or inaccessible" error messages. If I go to task manager, sometimes no firefox.exe is there, sometimes it is and I cannot close it. In either case I still can't start the program.
I tried reinstalling firefox, which did not fix the issue. I've also tried creating a new profile, again to no avail. AVG picks up no malware. I did a system restore to a week ago, which seemed to work for a while, but the problem has started again. I'm looking for a solution other than installing an old version, if possible.

Do you have the Firefox icon on your quick launch? Right click
on it, and select '''Open New Window.''' Sometimes this works.
If it opens, close it by '''Menu > File > Exit.'''
This is not a cure but will make it easier if Firefox locks up in Windows.

Firefox hangs after a few hours. The task manager shows it using 50% of the time, and I don't see where it's doing anything. What is going on?

It will not respond to any mouse clicks or key presses. I use the task manager to shut it down. When I restart, I select the option to restart Firefox with the same tabs and it does that and runs fine for a few hours and then it hangs again.

There may be a problem with one of the files that stores details of installed extensions. Try deleting these files as shown in the "Corrupt extension files" section of this link - https://support.mozilla.com/kb/Unable+to+install+add-ons
Though that article is not specifically about your problem, the method shown in the corrupt extension files section may help. When you restart Firefox after deleting those files, the list of installed extensions is rebuilt and this will hopefully fix your problem.

When opening an XPS file, IE hangs. Task manager shows XPSViewer.exe taking 50% of CPU.

I've seen this twice now on older XP machines (sadly, some of my users DO have to run XP) so I figured I should document it, if only because the fix is so non-intuitive.
By default, XPS documents open in IE with a helper called XPSViewer.exe. You can also open them in a separate standalone viewer by installing the Microsoft XPS Essentials thing
http://www.microsoft.com/en-us/download/details.aspx?id=11816
But that doesn't work in IE, and my users needed it to.
Sometimes, users report that when they open an XPS file, the browser hangs. Checking task manager shows that XPSViewer.exe is taking up 50% of CPU cycles. Ending the process allows IE to respond, but the document is not displayed.
The first hint at a solution was from:
http://discussions.citrix.com/topic/273861-cannot-open-xps-files/
"This issue occurs because the non-administrator user account cannot access the %WINDIR%\System32 folder. By default, WPF writes the output file to the %WINDIR%\System32 folder. The %WINDIR%\System32 folder requires administrator permissions.
When the non-administrator account tries to access this folder, the WPF caching code is triggered. This code causes the screen to flicker.
In 32-bit versions of the Windows Server 2003 operating system, the output file is D3d9caps.dat. In 64-bit versions of the Windows Server 2003 operating system, the output file is D3d9caps64.dat. "
It got me thinking that maybe i could modify the rights to the file instead of applying the hotfix...
After doing that the user could open the .xps file successfully!. But after closing the xps (internet explorer uses xpsviewer.exe to display the file) the file d3d9caps.dat disappeared from the system32 folder...
The next time the .xps file was opened by the user, the d3d9caps.dat file was not created in system32 folder as one might expect, but instead in the more appropriate path "...Documents and Settings\username\Local Settings\Application Data" folder.
So in fact, all i had to do to fix this problem was deleting/renaming the d3d9caps.dat file in the system32 folder.
So all you have to do is delete (or for safety, rename) that d3d9caps.dat file and try again! Works a treat!

In the %WINDIR%\System32 folder, find d3d9caps.dat or d3d9caps64.dat
and rename it to anything. Bamn. Fixed. That easy.

Whenever I shut down iTunes on my computer, it keeps reopening and I have to go into Task Manager and end the process in order for it to stop doing this. I am running it on a Windows 7 Home Premium 64 bit machine.
