I am being told other places to get rid of FF - is this what the official support is recommending ?

Youtube currently uses the HTML5 player.

https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues

Nothing on that page says, here is what you do to play HTML5 videos on Youtube.

Almost a moot issue. I don't get to watch election results tonight, which is what I badly wanted.

Going around in circles on the support pages...

I was having some video issues on ESPN and did this:

Type about:config in the Firefox address bar. Confirm that you will be careful if the warning prompt spawns. Search for dom.ipc.plugins.asyncdrawing.enabled. If the preference's value is true, set to false.

It worked for me! I agree though... I'm so sick of things not working in Firefox.

it was already set to False... But I do appreciate it !

I called for more help.

I installed the addon "HTML5 Video Everywhere" and disabled the YouTube Flash Player and the problems seem to have all been solved.

See the image I posted for the final mix of Addons that are working and not bothering HTML5.

Noe the Flash Player disabled.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.

Done. Solved.

I am not seeing on this page where to mark the post as solved.

Anyone ?

You go to the response that answered the problem. To its right is a link called Solved Problem.

On my screen I don't have any links that look like that...
