I'm new for ubuntu, using firefox-11.0 in ubuntu-10.10, recently I removed ffox-3.6 and installed ffox-11.0 from superuser. Even I cann't find update options in firefox preferences > Advanced > update...
there is no "Firefox updates:" option, only there is Automatically updates: search Egnines.
How can I find "Firefox updates:" option in "firefox preferences > Advanced > update" tab.
