Formatted my phone but playing videos still lags and stutters on Firefox browser on my Samsung. Only happens on Firefox, I've tested on Qwant, Duckduckgo and Brave and this problem doesn't occur. What might be the problem and solution? It's interesting that sometimes the video plays fine until I unmute it. Sometimes the problem goes away after I stop and play or refresh the page. I often have to play the video on a different browser. So, videos work fine on other browsers so I discart being a phone problem. But on my other phone this problem doesn't happen with firefox. I've been for several months looking for help/answer/fix for this issue. And I've been with firefox for ever and I don't mind minor bugs and problems but this is starting to be a bit annoying and more and more I feel like I need to move on to a new browser.
