Well, are there any lock files in there it's not finding? Or is firefox complaining for other reasons?

I have deleted all the lock files with above mentioned script.
Now, there is no lock file.
I am unable to figure out why it is complaining.

If it is running, but not responding, what good would removing lock files do? Maybe you should kill it?

I restarted the system but still it is giving the same error.
I removed lock files because this user is not local user so due to multiple instances it could cause the problem.

OK, thanks.

And you know that the lock files are in that directory, and go by that name?

Perhaps we could start by simplifying that code?

find ~/.mozilla -name "*lock" -exec rm -v {} \;

It's a bit more robust than using for something in `everything` to process a list of things.

Yes, I know about it. But even after removing the lock files, I am unable to access firefox.
