Why are youtube videos choppy?

more options

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

Chosen solution

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).

The new Firefox 64.0.2 update may help with the Youtube stuttering.

Yes, 64.0.2 fixes it for me :-)

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?

Here it is May, and the Firefox software still has not been fixed. All the others work OK. Where are the competent software designers at Mozilla?
