Форум поддержки Firefox для Android

I'm seeing glitches when scrolling on some sites, eg. google.com, orange.pl. I checked other browsers - chrome and Samsung internet (so based on chromium) and there seems to be no problems.

Dear Firefox team,

Since the two or three latest Updates of your browsers, a strange bug occours everytime watching a video. When I pause it and let it play again, the video goes under quite some lagging/stuttering. The audio is fine, but the video is not on screen is not. I have to go back on the video bar, so it runs smoothly again.

And before it comes, I already tried the usal methods, such as clearing the cache, clearing browser history, cookies, used privat tab, deibstalled adblocker etc. Nothing worked, and it happens even with different versions, such Firefox normal, nigtly, waterfox etc. And with every video player, not just a specific one. And I teued it on two different smartphones. Is there any solution or planning to fix this?

YouTube videos cannot be played in 4K resolution on Firefox; the maximum supported resolution is 1080p. However, when using Chrome browser, 4K playback is supported.
