Hello, its not really a question to ask in the community is more a bug in the software system which is firefox, The bug is after the last update, its october 8 2024 right now so figure wat the last update was, I noticed a big amounts of bugs with looking at videos, they always tend to pause randomly or dont play from the beggining, i promise you its not a problem on my end which i tested by finding that restarting the browser when i encounter the problem can fix the issue temporarly, so when i look at videos i mean - Youtube, twitch, instagram stories. it started with the new update i promise, please check it out. I wish you a great day, thank you for paying attention.🙂‼
