Hi check this bug report, it might help you:
https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/386810

Or simply try reinstalling firefox AND xulrunner:

sudo apt-get --reinstall install firefox-3.0 xulrunner-1.9

You could also run:

mv ~/.mozilla ~/.mozilla_old

Then rerun firefox to see if its profile related rather than the (garbage) app.

If it works with a vanilla profile, you have 2 choices

1) Rename the folder back (rm -rf ~/.mozilla; mv ~/.mozilla_old ~/.mozilla) and troubleshoot the bad profile (hard)
2) Keep the new profile and rebuild (possibly getting bookmarks from the old profile if necessary) (easy)
