This has happened before, and I'm not sure what the cause is.
So, i use Firefox, and whenever my laptop needs a software update, i close Firefox and any other programs i have open. But then, sometimes after a software update, I'll try to open Firefox again, and a message will pop up (i wasn't able to get a picture because i didn't know my computer would mess up) saying that Firefox is already open, and that i need to close it, restart the computer, or use a different profile. I restarted my laptop, and this screen popped up.
I know i had troubles with this screen before, and i posted a topic asking for help for it, but i think this problem might have to do with Firefox this time, which i why i created a new topic.
Last time i had trouble with this, i had to reinstall Zorin. I really don't want to lose everything on my laptop. Is there a way to fix this so it stops happening?
