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?
At that prompt you see, type exit and hit enter.
Once you do this, it will show what the actual error is. Can you relay that here?
You will probably need to run fsck on your machine.
It is not Firefox that caused it. It is likely due to a mechanical failure within the drive. This is not the only thing that can cause it, but is among the likeliest.
Running fsck usually can find and correct bad sectors on a drive. Most people do have bad sectors, so it is not the end of the world... Usually... It may indicate imminent hdd failure though and should be taken seriously and plans drawn up to replace the drive when able.
If the code for Firefox happens to be written in a Bad Sector, it is the app that will show the symptoms.
Moving the code and quarantine the sector are the most viable options.
In baseball, a strike is a pitched ball which the batter fails to hit. The batter is out after three strikes. The same can apply if you are naughty 3 times on this forum i.e. you are kicked out.
