Firefox not running after forced log out
 

Following Problem:
I am only using Linux at university, so I'm basically beginner. Today for some reason after logging in the the power of the computer went off.
After restarting and logging in again I couldn't start my firefox (which was running before).

Now I don't know whether it is because I'm still "logged in" with the old account (since logging in on several computers/terminals is no problem), or anything either more trivial or a real problem...

Is there any way to find out if I'm logged in on another terminal, and if how can I close this one (external log out possible)?

The university employs an RedHat scientific unix version (2.7..)

Greetings and Thanks

What exactly does "doesn't start" mean? That's a little vague, isn't it? It usually helps to give as many details as possible about what you've already tried. How are you trying to run it, and what response do you get, if any? If you haven't tried launching it from a console yet, do that and see if it gives you any output.

I generally get a "profile is in use" pop-up dialog whenever I have similar problems with unclean shutdowns. Usually in cases like this it means the browser just didn't have a chance to delete the "lock" file in your profile directory when it came down. If you find one there, simply remove it and try again.

BTW, there are also two command line options, -safe-mode and -ProfileManager, that you can often use when you have problems. The first will run the program with all extensions disabled, and the second launches the profile manager, where you can create and/or delete profiles. If nothing else works, you can always create a new profile to use.

Well,
the message was "Firefox is still runnig, ..."
but there was no process listed.
I tried that you recommend and it works again, so thanks alot.
