Msg. says Firefox is running but I can't access it and cannot stop it
When I try to access Firefox, I get a box in the middle of my computer screen that tells me Firefox is running and I need to close it in order access Firefox - or I should restart my computer. I have restarted my computer at least 3 times, but I still get that same message when I try to access Firefox. I have also shut down my computer entirely, and when I start it again I get that same message about Firefox.
This happened today after I installed Kaspersky Internet Security, which I have since uninstalled.

See:

Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
First, check your firewall settings. Go to the options and make sure that the firewall will tell you that a program wants access to the web. Then check the program list in the firewall. Make sure that the programs you want to access the web are set to ALLOW. If it is on AUTO, it may not have access.
===========================
Sometimes when FF is closing, not all of it shuts down properly. On Windows, start the Task Manager (Other systems may have different names). Select Applications (list of what user programs are running). If you see Firefox listed, try to shut it down normally. If it does not shut down, then on the Task Manager right click FF, and select End Task. However, if FF still does not shut down, or FF is not listed as running; on the Task Manager, select Processes. Look down the list for Firefox. Right click and select End Task. If this problem keeps coming up, ask for more help.
