Recently anytime I've tried watching videos on Youtube or Twitter on my desktop PC I've been having issues. On Youtube, It takes about 5 seconds to start a video (including ads), 5 seconds to load up a place I skipped to in the video even if it's loaded, and if I go to the start of the video sometimes it won't even try playing. On Twitter, videos are hit or miss, most won't play, and others will autoplay but will stop working if you pause or skip. Tumblr and TikTok work fine. I've tried running a private tab (disabling extensions) and still have issues, I've tried turning off hardware acceleration, clearing data, and even reinstalling Firefox. I tried both Twitter and Youtube on Chrome and video playback worked just as well as Firefox used to. I also updated my video card driver to see if it'd help without luck. I have great internet that I haven't had recent issues with either to cause loading problems. I hope to find a solution soon, I haven't found anyone else sharing this issue yet, but that I've found, it's Firefox. If there's any additional information that'd be helpful that I can get I can try getting it.
