My profile keeps disappearing after I close Firefox. In order to open it back up, I have to keep re-creating a new one. How to fix?

I've already uninstalled, and reinstalled Firefox, and no dice. If I don't re-create the new profile, I get the error message that the profile is missing or inaccessible when trying to open firefox. I have to open the browser by clicking on the new profile I just created in the profile manager box.

This can be caused by a problem with the profiles.ini file.
It is probably best to delete the profiles.ini file to force Firefox to create a new default profile

You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

*Windows: %AppData%\Mozilla\Firefox\ C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

After I close Firefox, it will not open again unless I restart my computer.

When I close Firefox normally, I cannot open it again unless I restart my computer. Why?

Yes, that is a strong indication that Firefox didn't close completely.
You can check that in the Task Manager (Ctrl+Alt+Del). 
If you see Firefox and plugin-container processes then you can close (kill) those processes and you should be able to start Firefox after having done that.
There are other things that need your attention.
Your system details list shows that you still have a very old Flash 9.0 r45 plugin installed that you should remove.
*Shockwave Flash 11.7 r700
*Shockwave Flash 9.0 r45
This plugin might be installed in the plugins folder in the Firefox program folder.
*(32 bit Windows) C:\Program Files\Mozilla Firefox\
You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of enabled installed plugins on the about:plugins page.
*http://kb.mozillazine.org/about:plugins
See:
*http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins
You can open about:xxxx pages via the location bar like you open a website.
*http://kb.mozillazine.org/about:config
It is best not to leave that pref set to true as it exposes that full path to web servers via the navigator.plugins object, so reset that pref to its default value false after you are done with the about:plugins page and have located the old Flash plugin.

Bookmarks got deleted on firefox 4 installation and i cannot restore them or add new ones. how to fix?

ok so the other day i upgraded my firefox to 4 but when it opened i had no bookmarks and could not even add new ones or restore ones from previous days. I cannot drag website onto the bar where you could have button shortcuts either. I would really like to know if i could fix this because I want my bookmarks back.

hello 43kogjvdl94, maybe the file in your profile that holds your bookmarks and history got corrupted. maybe try to rename/delete it so that it will be regenerated (please make a backup first before you proceed): go to ''firefox > help > troubleshooting information'', click on ''profile folder/show folder'' and close all firefox windows afterwards. a windows explorer window should open up - in there rename the file named '''places.sqlite''' - and restart firefox again. your history will be gone, but you should be able to restore your bookmarks through the bookmarks library > import & backup > restore...

My bookmarks disappear when I close Firefox. I can get them back by reloading them from a backup file but they disappear again when I restart Firefox. I've tried the "taskmanager, Process, Firefox.exe, stop process, and it doesn't work.

This occurs each time I start Firefox. The bookmarks work OK while I am using Firefox and you can add to them and save them to a HTM file. The html doesn't work for backup. When you go to organize bookmarks and try the restore function, as in "Restore Sunday October 24, 2010" you get the following error message '''''Unable to process the backup file."

My popup blocker exceptions disappear when I close Firefox.

I just ran into this the other day, but it's become a major issue. The exceptions I enter into the popup blocker don't persist from session to session; as long as at least one instance of Firefox remains open the exception list is there, but after I close Firefox and reopen it I have no exceptions left. I only need a handful of exceptions, but I don't want to have to type them in every time I access those web sites!

In case you are using "Clear history when Firefox closes":
*do not clear the Site Preferences
*Tools > Options > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings
*https://support.mozilla.org/kb/Clear+Recent+History
Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

If you use cleanup software like CCleaner then check the settings for the Firefox application.

Don't know the name of it but a toolbar at the top of the window has disappeared after I restarted Firefox. It contained add-ons such as Download Helper and I don't know how to get it back. Please help. Thanks!

Sometimes when I close Firefox and try to open it in few moments it shows me message "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." However, I haven't opened any additional Firefox related programs, and previous Firefox is closed. First I though it is because of my computer, but then I discovered that other people have the same problem as well

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.

If I close Firefox, I cannot re-open it. It appears to remain on in background.

I I close Firefox, I cannot re-open it without first shutting down and restarting the computer.

Seems to be a semi-common problem but I doubt you need to restart your system (although) that will do it. I have the same issue at this point.
Option 1: Use Task Manager (ctrl+shift+esc) and look to see if Firefox is still listed after you have closed it and cannot restart it. Right click and choose end process. Be careful to only shutdown firefox.exe unless you know what you are looking for!
Option 2: Simply Logoff your computer and log back on. This would be quicker than a restart.

It sounds like you restored from an old back-up. Did you back-up just before your software update? It will use your last one and if your last back-up was a ywear old then it will use that one.
In general, if you are getting these messages on your iPhones select logout (when you get that Apple Id request) and then log back in with your newer ID.
Sorry for your losses.
Cheers

When I close Firefox, then later want to start up again, I get I message that Firefox is still running. With "START TASK MANAGER", I need to close Firefox in order to start again.

I have the same problem. Firefox won't unload regardless of how long I wait. Literally hours ... I must go in and 'end the process'. This has been a real hassle for a while now. Even considered giving up on firefox. Please look into this! An additional problem; I have to run firefox to get the updates, but I can't get the updates to take because I can't get firefox to unload so I can restart it.

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