my firefoxie is not dead , it crashed after ubuntu "sekrity" updates
Maybe is the google extension ...don't know yet ...
I tried to delete them from extension dir , Yah not so simple.
Until is solved i will use epiphany
That is Faast!
Update : is an known bug , so i downgrated to previous version

sudo apt-get install mozilla-firefox=1.0.2-0ubuntu5 mozilla-firefox-gnome-support=1.0.2-0ubuntu5
