Hello mine,

just to make sure; is this the message you're getting :

" Firefox is already running, but is not responding. "

If so, it looks you've already read this article :

https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding

May I ask if you're using Kaspersky by any chance ?

And if so : would you disable it to see if that will solve the problem ?
