Random twitch streamers just muted forever

i already tried to delete the cookies and cache, but 1 user is still muted for no reason and everyone/everything else works fine, so is there something wrong with the browser ? i basically got like 2-3 completely different users muted for no reason, but at the moment i can only remember 1 of them and noone else has been added to the bug list ever since... and it basically happened when the Firefox itself got really low on memory again and started to display that red crash button. and even then, many different users crashed, but some did not even get the sound back anymore, while others did with no issue.... ps. i also found the other streamer now and both of them i was following, so that is also really weird, plus i havent noticed anyone else getting muted again, so maybe its just the ones that i followed ??? (and during the red crash button then) (specs are probably in the other "Firefox memory fail" thread)
