User Agent here: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0

Steps to reproduce:

watch any youtube video at 720p resolution. I didnt research other resolutuion. 720p is my used default.

Actual results:

video freezes after a few mins in but audio keeps playing in background.


Palliative solution:

I never had this problem but I start to have it now after update Firefox to version 60.0 (I use FF for more than 4 years).

The only solution I find until now is to use a Addon called "h264ify" which forces youtube to use h.264 codec instead of VP8, VP9.

Multiple reporters appear to have this issue with 60.0.

What processor do you have?

Could you please try setting media.wmf.amd.vp9.enabled to false?

In the URL bar, type about:config
Then search for media.wmf.amd.vp9.enabled the right column with the value will contain true, change it to false.

This disable the AMD 580 hybrid vp9 decoder. It seems that it has recently regressed greatly in new AMD drivers.
Used on give significant improvement, but no longer it seems.

We plan to disable it in bug 1461268
