I think that I'm pretty much done with FireFox and this may be the last straw. When I try to open Firefox, I'm getting the error message "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I tried all of the things that I could find on the web. There's no process running, so can't kill it via "Force Quit". I tried deleting the .parentlock file, using terminal, which seemed to be an approach that others suggested, but there was no such file. So, I'm stuck. Before I just completely give up on FF and move to Chrome, does anybody have any other ideas that might work?

Firefox crashed on me yesterday (2 Dec 2018) and does not open at all now, so Safe Mode is not an option.

Have tried: (1) closing and restarting Firefox; (2) restarting computer (MacBook Pro, Mid 2014, OSX 10.13.6); and (3) trashing Firefox, emptying trash, and restarting computer again. No luck. Continue to get the same, "We're sorry. Firefox had a problem and crashed," error prompt.

Per the instructions at https://support.mozilla.org/en-US/kb/firefox-crashes-troubleshoot-prevent..., I am pasting my most recent Submitted Crash Report here: Crash ID: bp-550e8b76-0c74-487f-a901-7abc70181203

Any help would be appreciated.

Thanks, Brandon

I like Firefox but sad to say that I have increasinlt wasted much time lately with its crashy ways and I made the mistake of using Refresh today.

Now get a message when I try open the app saying "copy of firefox is already open" which it is not true and it is not showing as running on the system.

I have tried reinstalling and it makes no difference.

I dont have an IT engineering degree but how do I fix this before I just give up and walk away? Thanks.
