I watch a lot of TV shows online. Netflix, Hulu, TV websites like AMC. Recently(within the last few months), I have had to start watching these shows on Chrome or Edge because EVERY video is choppy on Firefox. I can have both Firefox and Chrome open to the same site at the same time and Chrome is silky smooth and Firefox looks like it is stuttering.
