Why are youtube videos choppy?

Posted

YouTube videos are jerky/choppy on Firefox like frames are being skipped every half a second or so. Audio is fine.

Video and audio are fine on MS Edge.

Are there some settings I need to tweak?

I'm on version 64. I think this is a fairly recent problem but can't be sure.

Thanks, Jim

I installed h264ify and it made no difference. Then, I disabled H264-video-codec plugin...and now everything is smooth!

(I also tried just disabling the h264-video-codec, but h264ify is required for smooth playback.)

Thanks!

It might be a bug in the default codec.

It's fixed on Beta, so you won't need an addon after the next release (2019-01-29).

I have the same problem with jerky playback. Going to the same website using Windows Explorer runs smoothly. I have installed 64.0.2. Is there anything else I can do before dumping FireFox?
