For the last several days, YouTube has been increasingly unusable. The most obvious hindrance is when playing/pausing a video, or attempting to adjust volume using the native control overlay on any video. It lags substantially, my cursor often disappearing entirely & attempting to pause or resume playback takes several seconds. Using Firefox's task manager, YouTube is monopolizing roughly 2-3 GB of RAM when playback is paused, and CPU consumption will range from 0-95% - when playing a video/utilizing the tab, it tends to stay reliably closer to 50-100%. I have also run Firefox Profiler while resuming and pausing a video, which is here: [https://share.firefox.dev/49H9UyY Profiler Data]. I am not particularly literate with this kind of data though, so I have no comment on its contents. My extensions, by comparison, average roughly 500 MB and no more than 1% CPU utilization at any given time. I do use uBlock Origin, as well as Tab Session Manager, cookies.txt, Honey, Fakespot, Ruffle, and TWP. I am sure this is far more of a YouTube problem than a Firefox problem, but are there solutions available? I have seen discussions on other platforms regarding the issue, but it seems like solutions are in short supply - telling YouTube to bias in favor of AV1/VP9 had no impact, and I'm hesitant to download more extensions to attempt to bandaid the issue. Thank you :)
