I'm not sure why, but this works much better in chrome for higher speeds (like 10x). In firefox the video simply can't keep up and if you pouse or use the progress bar the video won't play anymore.
Edit: Hey! Thank you for the reply! : ) I'm more than eager for this to work as I'm jumping from chrome to firefox. What have I noticed: in chrome, even at 1080p the speed goes over 10x no problem. But here in firefox the buffering can't keep up (?). If i reduce video quality to 320 sometimes it works sometimes not. After the progress bar trumps the buffering, playback stays choppy and it becomes hard to seek or even play the video.
**Disabled hardware acceleration and it seems to be working just like in chrome (where hw accel is on). RTX 4070. Why?

Great though I wish there was an option to add a specific key before the other controls, so for example adding Ctrl before Scrollwheel Up/Down
