i think problem is changed now. in the past frame is freeze but it still playing.
but for this profiler, it look like youtube need more buffer. but stats for nerd said it still has some buffer.

can you try this link https://share.firefox.dev/4bYQBlc

i captured profiler after i found problem. and i rewind youtube video to the beginning to where the problem happen.
i still not sure how to reproduce. but when it happen it will always happen at same video time.
for now my temporary workaround it refresh that page.
