My machine is 10 years old. With Firefox video playback on YouTube is choppy even at 1080p. With Chrome it's perfectly smooth.

If Firefox performed better for me I would have switched to it long ago. This is on Windows 10 btw.

Look into about:support, what does `HARDWARE_VIDEO_DECODING` and sibling features say? If it's off, you could try force-enabling video acceleration by setting `gfx.webrender.all` to `true` in about:config. I've had it force-enabled for years with no issues.

HARDWARE_VIDEO_DECODING does not exist but there's a bunch of rendering options. They are all set to default and available except for a few things like DIRECT2D is disabled and WEBGPU / REMOTE_CANVAS is blocked.

gfx.webrender.all was set to false. I will give true a try. Thanks.

So it's been a week. I have not noticed any issues with Firefox. I didn't even adjust this setting.

Everything is a lot smoother now than it was about 3-4 years when I last tried, even with the same hardware.

Happily using Firefox as my daily browser now.
