When I close firefox I find another instance of firefox running that points to an advertisement

When I close a session of Firefox I find another instance of firefox running (which I haven't initiated) this usually contains an advert.
I've checked that popups have been disabled, which it has been. I tried disabling add-ons but this had no effect.
Any suggestions would be appreciated.

When I click the icon to open Firefox it opens the program 2x. When I close it there is another one open behind it that I have to close. How do I fix this?

see question...

This thread has some solutions:
https://support.mozilla.org/en-US/questions/762043
The most straightforward seems to be: hold Ctrl and Left-Click on the Reload button. You could also Middle-click on the Reload button (e.g. "click" with the mouse wheel, if you have a wheel-mouse.) The thread above also has some other options.
Edit: you could also hold Ctrl and drag a tab next to itself to clone it, another suggestion from the above thread.

When my volume applet is open (habit) in vista it crashes when I close firefox

I use windows vista and have the habit of keeping my volume applet open as I always wear headphones and I'm always watching media. when I close firefox (now that I updated to 8.0) it crashes the volume applet. Trivial but annoying.

Upgrade your browser to Firefox 9 and check

When I close Firefox and open another instance of it to look at a new site I get a pop up window telling me Firefox hasn't shutdown yet.

When I close Firefox and open another instance of it to look at a new site I get a pop up window telling me Firefox hasn't shutdown yet. I am aware of tabs, but I prefer to just open new windows.
Do I really need a pop up window telling me that I just closed Firefox? Is there a way to disable it in options? I can't even use Buzof program to auto click for me. I've never had this issue with any other browser and I find it incredibly annoying.

I am not clear what you mean by:
''the program will only alow 1 website for each time I boot my machine,''
Are you talking about Firefox or something else in the above statement. Firefox will, or should allow you to open quite a few tabs at startup if you wish, although it will be faster the fewer that you do open.
When you say
''I close it the program does not completely close ''
Again what is happening, what error messages if any do you see, and what exactly makes you think Firefox is not closing properly.
Presumably you have already clicked on the blue links in my first post and read those articles.

Firefox is freezing. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox still running. I close Firefox in Task Manager & can re-start Firefox.

Firefox is freezing in the middle of a browsing session. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox to still be running. Once I close Firefox in Task Manager, I can re-start Firefox. This can happen several times in the space of a few hours? I'm running Vista Home premium with Firefox 3.6.16, and this problem has only started in the last 4 weeks. Can Anyone Help? Core 2 Duo E7300 with 4GB RAM.

Sounds like it is hanging when you exit and later try to restart Firefox.

Where can i find the option of, when i close firefox that he saves my current tabs and when i open my firefox i will still have them?

Where can i find the option of, when i close firefox that he saves my current tabs and when i open my firefox i will still have them?

Firefox 4 and later versions save the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
Use "File > Exit" or "Firefox > Exit" (Mac: "Firefox > Quit Firefox") if you want to restore multiple windows or otherwise have problems with restoring tabs. 
You can use "History > Restore Previous Session" to get the previous session at any time. 
You may need to click the orange/gray Firefox button to see History. 
There is also a "Restore Previous Session" button on the default about:home Home page.
Using the "Show my windows and tabs from last time" setting is a more reliable way to restore session data.
* Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

When I close Firefox another Firefox browser opens. WHY and how do I stop this?

Every time I close Firefox another Firefox browser opens. Then I close that one and it stays closed. How do I stop it from opening a new Firefox browser on it's own?

Is it possible that you actually have two Firefox windows open and Windows 7 is showing one Firefox on the System task bar, but if you were wave mouse over that, you might see two windows.
To Close Firefox use File > Exit (Alt+F > Exit)
and not the X in the upper right corner which only closes the Window and may or may not close Firefox if it is the last window. The reason it does not always close Firefox is that there may be other tasks running so you don't see Firefox anywhere but in the System Task Manager on the Processes Tab which is where you can see if firefox.exe is running or not. Shortcut to Task Manager on Windows 7 is Ctrl+Shift+Esc (for other Windows systems Ctrl+Alt+Del , select Task Manager,...)

When I close Firefox then wont reopen unless I go to task Manager and close program from there.

When I close Firefox it will not open another window when you click on icons or manually try to open new window. I have to open Task Manager find Firefox program and manually close program. Then when you open a new Firefox window it try's to restore previous session , saying sorry Firefox crashed. I have uninstalled and reinstalled , turned off all add-on's nothing has worked. No virus's , no other outside influences , nothing else on my computer has issues. Can you help?

When I close firefox I cannot launch again without restarting PC. I deinstalled and reinstalled without succes

Only since a few weeks, when I close Firefox and after a wile want to use it again I get the notice that there is still a version running. I do not find this version and so I cannot close it. The notice advises to restart the computer. then the Firefox starts again. I uninstalled Firefox en reinstalled but without any change.

Hello fredakis, go for a '''clean re-install''', 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 https://www.mozilla.org/firefox/all/ (full installer) and save the setup file to your computer.
#After the download finishes, close all Firefox windows (or open the Firefox menu [[Image:New Fx Menu]] and click the close button [[Image:Close 29]]).
#Delete the Firefox installation folder, which is located in one of these locations, by default in '''Windows:'''
* C:\Program Files\Mozilla Firefox
*C:\Program Files (x86)\Mozilla Firefox
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.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank 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

I can uninstall firefox then reinstall it then it opens when i close firefox i get crash report then i have to uninstall then reinstall to get it to work.

I have tried everything. i have installed uninstalled it works the first time then when i close all windows and try to reopen i get a crash report. then i cant even open in safe mode. so i go through the uninstall and reinstall process again. this has been a nightmare. I hate chrome but may have no choice but to change browswers. I have had this problem before but dont remmeber what i had to change in the about:config settings to resolve.

If you have submitted crash reports then please post the IDs of one or more recent crash reports that have a "bp-" prefix:

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop https://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*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.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.

Hello Brian.
You don't need to restart your computer to open Firefox again: you just need to close it manually through your application manager (CTRL+SHIFT+ESC in Processes tab). Anyway, hopefully this support article is what you need:
http://support.mozilla.com/en-US/kb/Firefox+hangs
What's probably happening is that 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.

I copied this from your 5.0 download information: "All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again." When I opened my computer today all my apptabs from yesterday had disappeared. Why?

Your download page for 5.0 stated: All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again.
I liked the convenience of using App Tabs and was disappointed to find that the ones I had set up yesterday were gone today. Am I doing something wrong?

Works fine for me, I can simulate your problem by improperly closing Firefox.
The correct way would be to close the windows you don't want and then to exit Firefox through the File ("'''Alt+F'''") menu then use '''Exit''' or '''Qui'''t depending on your system.
But '''I can simulate your problem''' by closing the good window with "X" in the upper right-corner first (the one with the app-tabs) and then close the other window by any means.
You restart Firefox and open a window, since you closed without app-tabs there are none so you just see a window with your home page.
Firefox has some things added to Firefox 4 and therefore in Firefox 5.
# "'''Alt+S'''" (Hi'''s'''tory menu)
# "'''Restore Previous Session'''" (that's the window without the app-tabs, but you have to this first)
# "'''Restore Recently Closed Windows'''" -- can choose which window to reopen based on name and the mouse-over tells how many tabs. or you just use "'''Restore All Windows'''" without the guessing.
''I know you are on a Mac, and this affects Windows user more than anybody else, but it does affect other systems besides Windows, occasionally, perhaps more often now with the plugins container.''
The following may not completely eliminate having to terminate Firefox through the Windows Control Panel but it will come very close.
'''Plug-in and tasks started by Firefox may continue after attempting
to close Firefox''' The "X" in the upper right-hand corner closes the
Window (same as Ctrl+Shift+W) but even if it is the last Firefox window,
it does not necessarily close Firefox .
The only '''proper way to exit Firefox''' is to use '''Exit''' through the
File menu, not the "X" in the upper right corner of last Firefox window.
In the Firefox 4 and 5 that would be Alt+F then X

Use the '''Windows Task Manger''' to remove all running firefox.exe in the "'''Processes'''" tab of the Windows Task Manager, then restart Firefox.
If Firefox will still not start, remove the parent.lock file from the profile which is created each time Firefox is started to prevent other Firefox tasks from running, see 
http://kb.mozillazine.org/Profile_in_use#Remove_the_profile_lock_file
'''Avoiding Problems with close/restart''' ''choose either extension''
:Use to close and restart Firefox after enabling or disabling an extension, switching to a new theme, or modifying configuration files, then you don't have to worry about delay or have to look in the Task Manager to see if Firefox is closed yet.
Both extensions use the same keyboard shortcut "'''Ctrl+Alt+R'''" or a file menu option.

I want to delete all cookies when I close Firefox except for one website. Is this possible?

I have a website bookmarked that I use frequently and I have set my preferences on the site. I have Firefox set to allow cookies from this site. Is there any provision to delete all cookies except this site when i close Firefox?

There is a plugin for that, search "cookie" on the plugins site and you'll find it.

I want to add a message when I close firefox reminding me not to forget my memory stick

I'm using the latest version of firefox portable on a USB memory stick. It is a fresh install today. I work in different places and I'm worried about leaving my memory stick behind. I was hoping there was some way of adding a notification when I close firefox reminding me to remove my memory stick. I have searched the add on site and forums but cannot find an answer.
Is there an add on that might help?
Can I change the text of the "are you sure you want to close firefox" notification to something else?

For Windows computers, write a batch file. The first line would start Firefox.
The rest of the batch should be your reminder. Add a '''Pause''' command
at the end of the batch, or the message will just flash and disappear.
If you want some guidance on this, just ask.
