when I try to reopen Firefox, it says its already running and to restart my computer or close it down. But, it isn't open. This just started when I downloaded the newest version
I open Firefox, use it then close it. Next time I try to open it, I get a message saying its already open, but, it isnt. I have to constantly restart my computer to use Firefox. What can I do to fix this?
A few times a week
== I downloaded the newest version of Firefox
