YouTube videos doesn't want to load.

YouTube videos don't load, but if they do then they stop and just buffer. It works on Microsoft Edge. Sometimes even sites doesn't load...

Same. 128.0 version. YouTube videos are buffering very often. On other browsers it is ok. Maybe it is cause by playing videos at 1.5-2x speed, so firefox sometimes waits too much time. In YouTube Shorts speed 1x and all is ok.
