Another case of dev chasing money and completely trashing on the userbase. Take a look at the github page to see them circlejerk. I recommend checking out other options instead of using this broken mess. If you want to see other reviews, filter to only 1 star to see actual reviews instead of 5 star bots.

I hope whoever at Mozilla is in charge of putting the recommended label on addons will review this update and consider removing it from the list of recommended extensions.
