Firefox 11 issue

Most of the time after exiting firefox I will get an error message when I want to restart...

"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"

I usually go to the terminal and use the 'killall' command to restart.

Why is this happening and is there something I can modify ?

Most of the time this happens due to the app not shutting down properly an remains running in the background.

You will need to show hidden files Ctrl+h (most file browsers) or click view > show hidden files.

Check in ~/.mozilla/firefox/your-current-profile-directory/ look for "lock" and ".parentlock" files an delete them if they exist.

In case you are unsure, "~/" = "/home/your-user-name/" directory....

Let us know.

This can be solved:

A - Manually
1) Find your profile. It will be at /home/[username]/.mozilla/firefox/[Profile name]/.
The hidden file(s) and folder(s) can be made visible by pressing the Ctrl+H in Nautilus.
2) Remove the lock files. You have to remove these two files: lock and .parentlock.

B - Killing the process
1) Open a terminal and type the folowing command: ps auxwww | grep firefox. This will tell you what process number Firefox has.
2) Then type this command: kill [processnumber].

Good luck!

I only see a parentlock ... which I deleted.
I was able to restart after deletion.
However, after that I was having the same issue ... parentlock returns and sometimes deleting it doesn't help.

Sorry, but which one of these is a process number to delete ?

Code: Select all

 $ ps auxwww | grep firefox
username   2179  2.2  4.2 186624 65136 ?        Sl   08:27   0:04 /usr/lib/firefox-11.0/firefox
username   2206  0.0  0.7  53192 12332 ?        T    08:27   0:00 /usr/lib/firefox-11.0/plugin-container /usr/lib/mozilla/plugins/ -greomni /usr/lib/firefox-11.0/omni.ja 2179 true plugin

Try this...
Menu/Administration/Systems Monitor/firefox. (may show 'sleeping')/end process.

I end process and i can restart firefox ... but if i exit firefox it will not restart unless i go back and either 'end process' or 'killall firefox'. This happened after the version 11 update ... I used 3.6 for a very long time without a glitch... ever since the last auto updates, firefox has had some issues on my system.

I wonder whether you are using any FF extensions or plugins that prevent FF from quitting normally.
You may try renaming /home/[username]/.mozilla/firefox/(or back it up and delete it), and then start FF and restart system to see if the symptom reoccurs. If not, there is something wrong with your present profile.
