Hi

Since today I cant watch netflix anymore on firefox browser, but on edge and other browser.
The problem: I go on Netflix, I see all series I could continue watch, like the normal netflix site, I klick on one, still see the video preview playing, i click on play. Black screen and only sound.

Twitch, Youtube playing fine.
edit: restart didnt work,
if there are, I am not aware of any recording tools running exclusively in firefox (All other browser work)

had a short idea, but it made no sense at all because netflix is running in all other browsers,
but my idea was it could have been because I did take a screenshot in Word with alt + print, or maybe a snipping tool still running.  But that wasnt it.  Wouldnt have made sense because neither do record the screen permanently.
