ok so i love this add-on... on chrome. the audio quality starts glitching out on anything over 2.00 speed on firefox. i usually watch youtube videos at 2.50+ but i can't deal with the robotic sound on firefox. however i really do prefer firefox and would rather switch over to firefox, but this video speed issue is the only thing stopping me. not sure if it's an add-on problem or just a firefox issue that can't be helped.
