High playback speed (x3) breaks when holding arrow keys to skip to unloaded part of the video. It downgrades to youtube's playback speed and the addon's speed just doesn't work untill reload of the page.

Does NOT stop videos on background tabs from playing. Does NOT hide shorts. Doesn't do SHIT

it's almost perfect but i'm missing a few tools still like flipping something from portrait to landscape view etc.
Fix those things and you get a purrrrrfect 5.

Really useful, thanks!
