Firefox 7.0.1 doesn't exit completely on XP
On my XP system, when I exit Firefox 7.0.1, it doesn't exit completely. It is removed from the list of Applications shown in Task Manager, but not the list of Processes. If I try to restart it, it says it is already running and won't start up until I stop the firefox.exe process via Task Manager. This does not happen on my Windows 7 system. I have already uninstalled and reinstalled Firefox.

Reinstalling Firefox would do nothing for that. There are some extensions that can interfere. The main thing you can do is to close Firefox via file > Exit, or "Firefox" button > Exit -- it won't eliminate the problem, you may still have to terminate from the "Processes" tab of the WTM, but it will reduce need to. Closing Firefox with the "X" in the upper-right just closes the Windows like "Ctrl+Shift+W" but it does not necessarily close Firefox when there are subtasks running.
A lot of the time you probably simply want to close firefox and restart it again and for that the is an extension that puts that process into automatic pilot.
