Firefox does not start after latest update.

Asked by Achilles on 2009-12-21

After the latest update I get a window with the following message: Could not launch 'Firefox Web Browser' Failed to execute child process "firefox" (No such file or directory)

I have tried removing and reinstalling Firefox but it does not work under either Gnome or xfce. Firefox starts up normally, however, under fluxbox. I will be happy to send any other info that may help resolve the issue.

Clean firefox mozilla profile

Close all opened Firefox and try to delete your Firefox user setting open a terminal from applications → Accessories → Terminal and type:
mv .mozilla .mozilla_old
and restart Firefox.

If you have a lot of bookmarks please export them before move your setting directory, then import them again from saved file into Firefox.
Also take note of your installed Firefox extensions, to reinstall them.

if this works then delete the .mozilla_old directory, from terminal, type:
rm -fr .mozilla_old

hope this helps

Thank you for the prompt response. I tried "mv .mozilla .mozilla_old" but unfortunately it does not solve the problem. Firefox still does not start.

Open a terminal and type:

firefox or firefox-3.5

Copy and paste errors here.

typing firefox-3.5 brings back Firefox!

ok great, you can give a permanent fix with:

sudo mv `which firefox` /usr/bin/firefox_old; sudo ln -s `which firefox-3.5` /usr/bin/firefox

and it should be fine.

Thanks a lot. Problem solved. Link /usr/bin/firefox was broken, still pointing to firefox-3.5.5 instead of firefox-3.5.6
