Firefox stopped working, I cannot access the internet with it. I've tried changing the default settings time after time to no avail, so I decided to uninstall and reinstall, but all it does it tell me to close the program 1st, when it's not even running, so I can't even uninstall a program that I can't even use!

When you are checking the Windows Task Manager ("Ctrl+Alt+Del) are you looking at the "Processes" tab, looking at the "Applications" won't help.

Also close the plugins-container while there.

The following may not completely eliminate having to terminate Firefox through the Windows Task Manager 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 Beta 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.

very infrequent -- 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

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.
