Hi, Ive got FF version 115.2.1esr 64bit- Macbook Pro High Sierra.. I was watching amazon shows and movies until last night, started to get the message from Amazon, "Video Unavailable- We're experiencing a problem playing this video, for assistance, etc..." I pulled up Chrome and the movies are playing just fine there. I put FF in 'safe mode' and the video is playing, so what does this tell me? If I can play the movie in safe mode why not in regular mode? Keep in mind that I was watching other movies earlier in the day and nothing changed during the day, I didnt download anything new, just business as usual. So what do I do now if the vid plays in safe mode and not the regular mode?

Thanks very much for any help.
