This may sound a little weird but sometime Mozilla Firefox will not start. You click on Firefox icon and nothing happens. So how do you fix the Mozilla web browser if it will not start?
This may happen due to two following reasons:
a) Mozilla Firefox may be running and it is not responding at all
b) ~/.mozilla directory is corrupted while updating or installing an extension
Mozilla Firefox may be running and it is not responding at all
First see if Firefox is running or not by typing following command:
$ ps aux | grep firefox
vivek 3174 19.5 13.9 209040 107008 ? S 20:17 7:30 /opt/firefox/firefox-bin
If a process is running, kill it by typing:
$ kill 3174
$ killall firefox-bin
Now try to start Firefox
~/.mozilla/firefox directory is corrupted while updating or installing an extension
Just rename a ~/.mozilla/firefox directory
$ mv ~/.mozilla/firefox ~/.mozilla/firefox.old
Now try to start Firefox.
Please note that you can apply above procedure to other Mozilla products such as Mozilla Browser and email client.
