Melhorou a reprodução de vídeo do YouTube no meu notebook antigo. Agradeço aos desenvolvedores.

YouTube now defaults to AV1. The extension was last updated 6 years ago, so it still only blocks VP8/VP9.

EDIT: After changing this setting to false in about:config it works: media.av1.enabled

Jeżeli nie oglądasz w rozdzielczości wyżej niż 1080p to polecam zainstalować bo po pierwsze możliwy płynniejszy film, po drugie mniejsze zużycie prądu ponieważ stój sprzęt potrzebuje mniej prądu, a po trzecie jeżeli chcesz to możesz zajrzeć w kod tego rozszerzenie, czyli możesz zweryfikować że nie zbiera żadnych danych

THANK YOUUUU

Fixed my lag

Perfect. Got an i5 6300hq, was having ~50% CPU usage while watching 1080p@60fps. With this i got 25-30% CPU usage. Thank you!

Great improvement, in terms of keeping my laptop much cooler. Great extension. 👍

Finally videos don't get pale in full screen. Thanks you!

Installing this fixed hardware video decoding. Now Firefox uses much less CPU even when I watch 4K videos with VP9. Task manager shows HW video decoding works. It was zero before.

Still seems to work, finally no more choppy and painfully slow and in low resulution loading YouTube videos in Firefox, and no need to use YouTube in Chrome as a "workaround".
