Youtube videos stutter and lose audio

youtube videos/live streams don´t play smoothly like they do with firefox or chrome or even standalone players like potplayer.
They always start fine for a minute or two then stutter/freeze, jump several frames ahead and lose audio. Sometimes it recovers but mostly don´t.
In the video indicated below, video stops at around 5 minutes, audio resumes but not video.

It is better now with youtube addon 5.3.13 compared to previous versions, but still…
