Firefox proces don't close on exit, and i must close it manual.

Hello everyone, I from Poland., and i have this problem :
If I close firefox, proces : firefox.exe don't close and i must close it manual.
There is everytime when i close firefox normal.
Sorry for my bad english, i'm 14 years old.

This is usually caused by wither an extension, or anti-virus. What do you use for anti-virus on your machine (I've heard reports of webroot causing something like this).
You can try updating to Firefox 12, and if it still happens after that, Try to start Firefox in [[Safe mode|Safe mode]]. This mode disables all extensions, user customizations, hardware acceleration, etc. temporarily for diagnostic and troubleshooting. If Firefox works fine in Safe Mode, then this is likely an add-on issue. Restart Firefox in normal mode, then type "About:addons" (without the quotes) in the address bar. Disable your extensions one by one, restarting Firefox between each one, until you find the trouble maker.
and BTW, your English is great ;)

Firefox does not close when exited and I must use system to delete process in order to log in again.

When using either my XP or 7 computer and I exit Firefox and then try to get back in, I get a message that Firefox is already running and I must exit to log back in. I must go to the system to delete the Firefox process before I can get back into Firefox. I am using Comcast as my provider.

Every page hangs with Firefox 8, there is often no exit, and if there is, clicking on it does nothing. I have to use cntrl, alt, delete to shut down every single time I use Firefox 8.

I couldn't even open Firefox for hours, then realized there was an update to 8. Once updated, the horrors began. I can't exit a single page with Firefox 8. Every page hangs. I have used cntrl, alt, delete like never before. I disabled the container.exe plug in for Firefox, and still have problems. There is no menu bar, there is often not even an exit button, but when there is, it doesn't work. These problems must be fixed, or I'll never use Firefox again.

See "Hang at exit":

See "Firefox hangs when you quit it":
*https://support.mozilla.com/kb/Firefox+hangs
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.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Using firefox 7.0.1 in Win XP (SP3), firefox.exe still runs after I exit and I have to end this process in task manager in order to get Firefox to run again. Fix?

I tried exiting Firefox using the File|exit menu item or just killing the window and (of course) re-booting the computer to see if that fixes the problem. Is this perhaps an incompatibility between the latest version of Firefox and Windows XP? (I do not have a problem like this on my Win 7 Professional (SP1) machine.)

My Firefox tabs don't close at times. Why? Help?

So whenever I start opening tabs, the close button doesn't close my tabs. This usually happens when I have 4-5 tabs open. Then when I switch to another tab, I can't switch back to the tabs I want to close. This really is annoying because then I have to restart Firefox, resulting in none of my tabs being saved. It may be an add-on I have but I'm not sure. Please help!

That didn't seem to fix it permanently, I could really use some help on why this keeps doing this

I changed the "keyword url" setting in about:config to allow it to be used as a google search box, but when I exit and restart firefox it reverts to its previous setting.

chrome://browser-region/locale/region.properties
This is the URL that is in "keyword:URL" in about:config in my Firefox 4. I attempted to change it to http://www.google.ie/search?q= so as to use the address bar as a search bar. It works fine while Firefox remains open, but when I exit and come back later to open Firefox and use the address bar for search items I find that it has reverted to the default setting.
Can you please help me resolve this issue?
Thanks

You can start Firefox in [[Safe Mode]] to check if one of the extensions 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.
* https://support.mozilla.com/kb/Safe+Mode

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox 4 you can use one of these to start in [[Safe mode]]:
* Help > Restart with Add-ons Disabled
* Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

When I close firefox it doesn't close. I go to reopen it and it says that it is already running. I have to use task manager to end process to close it before i can log back on.

After browsing and I close Firefox it appears to close.
However when I go to reopen it later I get a message that Firefox is already open and I need to close it. The only wany I can close it is by using Task Manger to end process.

Must be the "hang at exit" problem. You already know how to do Step1; now just determine which Add-on (Extension or Plugin) is causing the problem.

Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.

Set homepage to My Yahoo close firefox and reopen and My Yahoo gone back to the main Yahoo page. I open wall street journal I need to log in everytime I exit and re-enter. websites with passwords, password does not show up. did not happen in Firefox 3.6

My baseball forum used to log in as soon as I open bookmark. Now must enter name password to log in. Exit page come back I have to log in again. None my user names passwords stay in the boxes or remain after logging out. I did not set the Permanent privacy mode and then I did set the Permanent mode and neither changes this. I have Accept cookies enabled. I have remember passwords checked. ???

Try clearing your Cookies for the affected websites. 
Tools > Options -> Privacy - Cookies = Show Cookies ''button'' 
Enter the domain in the Search bar at the top and all the Cookies for that URL will appear. Unless you can figure out which Cookie is for "remember me", you'll need to delete them all.
Hold the {Ctrl} key while you click on each Cookie in the small window. When that list is all highlighted, click the Remove Cookie ''button'' in the lower left. 
When you are done click Close.
If that problem persists, you might need to delete the __cookies.sqlite__ file in your Profile folder.

Suddenly, Firefox seems to have stopped deleting cookies and browsing history at close, although that is what I have always had selected, and selections haven't changed.

I have always had Firefox set up to delete cookies and history at close. I noticed today that it doesn't seem to be doing so.
I can shut down and restart, and still see prior history, and cookies are apparently still there.
The functionality has always been that if I'm in an email account like gmail, and I close Firefox, I have to log back in when I return. I noticed today that when I restart Firefox, I don't have to log into gmail, I'm still logged in, even though I didn't tell gmail to remember my info (and even if I did, that cookie should be gone). I don't think it's a gmail problem, because other browsers still seem to work correctly.
Thoughts?

Hey, these are the instructions on how to try safe mode. Please post back with your results.
'''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 turns off some settings, disables most 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".

'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow 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.''

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!

My homepage will load about 30% and then i'm dead in the water. when i close firefox it appears to close but when i try to reopen it tells me that it's already running. started with beta 6 i deleated and loaded ver 5 no change

when i start firefox, everything starts normal then my homepage (igoogle) starts to load, gets to about 30% and stops. from there i can click on links or bookmark and a new tab will open but no page will load. i can't get anywhere. then when i close firefox it appears to close normally but when i try to reopen firefox i get a message that firefox is still running but not responding and the only way to shut it down is to reboot. when it first occured i was running beta 6 (since it became available, i also used beta 4 & beta 5) i then uninstalled beta 6 and downloaded and installed ver 5 same problem. i then did a system restore to a time before the problem.. no luck. i'm not sure what to try next. IE & chrome both work fine

I'm in exactly the same boat - dead at blue screen, only option is to salvage using target mode.
I don't currently have access to another Mac to do target mode. I was planning to buy a new Mac this fall anyway, though. 2 questions in preparation for that purchase:
1) Is there anything I can do before buying a new Mac to make the salvage process more successful? ie, should I spend the time and money going to the genius bar to have them help me get from totally crippled to partially crippled? (As for expertise, I'm a proficient consumer-grade user, but Apple Support walked me through the safe-boot process, etc.)
2) Is Apple going to provide 10.5 once it is released to people who buy a new Mac in these 6 weeks pre-release?
Thanks for your help,
Bailey
