exception in torbutton_restore_nontor_settings
Hi when you disable or remove torbutton, and therefore, torbutton_restore_nontor_settings throws in exception and therefore, this.unregister is not called (in torbutton_uninstall_observer object).
exception is triggered by line: savprefs.setIntPref('socks_version', liveprefs.getIntPref('socks_version'));
by the way, adding a line for extensions.torbutton.saved.socks_version in defaults/preferences/preferences.js seems to fix that.a
