Hi, I have a problem with Youtube playback on my machine. Sometimes videos are playing and skipping few seconds, sometimes stopping/hanging and using a lot of CPU (I can hear CPU fan ramping up). It mostly happens when I play videos at 1080p and up. Sometimes video can start playing, then skip few seconds, play few more seconds and hang, sometimes after refresh it works fine, another time it works for like a minute and then again hangs/skips. I had this problem on FF 89, I've updated to 11x, still persisted, now I have FF 125.0.3 (64 bit). Things that i've tried: - enabling/disabling hardware acceleration in FF - enabling/disabling gpu hardware acceleration in Windows - changing some settings in about:config (fe. media.wmf.zero-copy-nv12-texture to false and gfx.direct3d11.reuse-decoder-device to false, and few more) - disabling and deleting addons

PC specs: AMD Ryzen 7 5800X, Asus Tuf X570, GeForce RTX 3070 (latest drivers), Windows 10 22H2

I use Sync on multiple computers for passwords. I have forgotten the Primary password on one of them. If I do a password reset on the one computer, does it affect the passwords stored on the Sync server, or maybe just the key4.db and logins.json folders on the computer being reset? I will not do a reset if the Sync'ed passwords could be affected, I'll just look them up on my phone. Thanks for your help!
