It does what it says perfectly, but I wish it also displayed a button on video player page (for example, next to Share button, or next to the autoplay toggle button). Two reasons for it:
1) I keep forgetting what the shortcut is and I shouldn't have to memorize it.
2) Surely it's faster to just click one button than press 3 keys on a keyboard (much more than 3 when you keep trying to guess the correct combo).

funktioniert wunderbar! genau danach habe ich gesucht.

Simple, works exactly as expected. Great quality of life improvement.

Works great and does what it says!

Seems to do the trick. I have too many extensions...
