not sure when "no longer" remark appeared, but accidentally finding out it hides 2/4K quality makes it not worth for me anymore.

I've used this add-on for years, but eventually I realized that as of 2024 this is what's blocking Youtube from playing any videos above 1080p. I don't know why, but no video on Youtube will show the option of playing above 1080p when this extension is enabled and plenty of videos allow up to 2160p when this extension is disabled.

Le son est sacadé

At first it was great, I had nice smooth 1080p playback on youtube, but now, for some reason, the max resolution I can set is 480p, and I don't understand why.

Does not work in Firefox. It can be seen from the power consumption, processor load and lags. Radeon HD7560D video card. Everything works fine in Chrome, EDGE decodes (informs) on n 264 by default. There may be a problem in the browser itself.
