Functionality is different for Fennec, to restart Fennec simply enable Restartless Restart, it will always be disabled.
Restartless Restart is similar to the QuickRestart add-on except it doesn't work on FF < 4, it does work on FF 4, it's restartless, it's 12KB instead of 34KB, it works for the latest versions of Fennec, Seamonkey and Thunderbird.
