Remove Battery API related bit in Torbutton
In #5293 (moved) we removed the Battery API preference (dom.battery.enabled
) from our custom prefs file, 000-tor-browser.js
. The rationale was that Mozilla made the preference accessible only by non-webcontent (see: https://bugzilla.mozilla.org/show_bug.cgi?id=1313580) and we therefore don't need to set it ourselves anymore.
We missed that Torbutton is dealing with the pref as well. We should remove that bit, too.
