Not one add-on working. Fucking pathetic Mozilla. These guys really are hopeless. As an add-on developer I have suffered first hand at their underhanded, ill-thought tactics. There is a superior attitude among Mozilla developers, that everybody else must change to suit them. Just look at the history of gmail.com support on Firefox for Android. I have also received personal messages from Mozilla staff pretending to be users asking me to upgrade my AddOns to WebExtensions, or giving me bad reviews. These guys are assholes.
Source code fork anybody?
