Firefox is already running, but not responding in Linux
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
It was the error message on my fedora 7 machine that had Firefox 2 installed. I was able to launch Firefox in my root user account but I was not able to do so in my non root user account.
I am not Linux expert but I always believe you can search any solution as long as you know what you need to search so I just goggled for this and got the solution and cause of problem too.
Cause of the problem is a bug that is in Firefox since version 1.5 and its solution is simple delete the old profile and creates a new one. Here is the complete process in steps.
1) Login as non root user.
2) Press alt+f2 it will give you a small window.
3) In text field of this windows type Firefox –p
4) It will open Firefox profile window.
5) Delete or rename the existing all profiles.
6) Create a new profile and make it default.
7) Start you Firefox and here you go. It’s should work fine now.
I got this problem in Linux (Fedora) but doesn’t matter if you have same problem in windows solution is same in windows also for this problem
If you are in windows for step 2 instead of alt+2 please user windows key+r and rest all the process is same.
Do let me know if you face any issue in this.
Hope it was useful for you.
