Youtube not working on 57.0

[wallythekat]

Since the beginning of 57.0 YouTube videos get stuck and/or run erratic on my Firefox. They run fine on IE.
Unfortunately my 'view page in IE' add on doesn't work either.
Please help

I'm still at a complete loss with my "live youtube" issue. Apparently 21 other people have the issue and no one has a clue: https://support.mozilla.org/en-US/questions/1190024

creating an entirely new profile doesn't work

your security software seems blocking yt3.ggpht.com.

no firefox problem.

Some URLs to these "live youtube"?

Have you tried Safe Mode?

Why does Youtube work properly on IE and not on Firefox 57.0? Same computer.....worked fine on Firefox before 57.0

thanks

upgrade to ff 58 beta. apparently the issue is fixed there: https://bugzilla.mozilla.org/show_bug.cgi?id=1362440

FYI, for the live stream issue related to 1362440 - [MSE] WebM segments with Tags elements not properly handled., a workaround is to set media.webm.enabled to false. At least I was able to start watching a live stream after getting an error in the player.

Video stream playing fine in 58beta without the workaround.

to Firefox with MSE. The videos play fine on Chrome, if we access the videos directly through Firefox (not through MSE), or if we remove the Tags element.
