When I close Firefox and then come back to it later a box comes up that says it's already running. It says to close Firefox first but when I hit close nothing happens and the box comes up again. I have to shut down my computer and restart to get into Firefox again. If I can't get this fixed I will start using someone else. Someone told me a way to close Firefox but I forgot what they said.

This happened

Every time Firefox opened

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:

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 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 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.
