Status: RESOLVED INCOMPLETE

Basic information

I switched from Opera to Firefox yesterday, and everything seems to be working fine until I try to play YouTube videos.

The first time this happened was when I was watching a YouTube video and an ad appeared; normally, I try to skip the ad, but the entire thing lags when I click the skip ads button.

Now, when I watch YouTube videos, I try changing the video quality from 144p to other resolutions, but when I do that, the entire laptop freezes. I tried clicking other tabs, still freezing, even programs I opened like Discord, still freezing, and I have to wait for maybe 10 to 30 seconds and try to close YouTube before it freezes my laptop even more. (This also occurs when attempting to switch to another YouTube video.)

Steps to Reproduce:

1. Open a YT video
2. Click another video in the sidebar.

Expected Results:

Fast loading of the new video.

Actual Results:

Slow loading/lag of the new video.

Ok, the profile looks a bit different after all.

The profile(s) look unusual. Somehow processes/threads are not getting run.

Per the discussion on reddit, have you tried updating your GPU drivers and Windows versions? It'll be hard to investigate further until we can rule out those casuses.
