Can Not play YouTube HTML5 videos, in SeaMonkey 2.48. This link will not

This does not offer me any solutions. The video plays just fine with
(yuk) IE. Any advice would be greatly appreciated.
You need to figure out why SeaMonkey 2.48 is not supporting any of the
available video formats for HTML5 playback. It should support them all.
My SeaMonkey does. My Fx 45.9 ESR was only supporting ONE of the
five on my default profile. I tried a new profile with very little
customization and it supports all of the formats. I spent hours trying
to figure out what the problem was on the default profile which is very
tweaked with lots of extensions and dates back to Fx 10 ESR so an old
profile that is partially corrupted probably as well as maybe something
I did long ago in about:config that is causing blocking of some of the
video formats. I finally got Fx to support 4 of the 6. Fx had a rare
crash a few days ago and it came back with some oddities. One being
that it now supports all six formats.
Try Safe Mode which will help rule out an extension as the problem.
Also try a new profile. If a new profile supports all of them then use
DuckDuckGo and do some research on each and see if you can figure out
what is wrong on your default profile and fix it. Also
Help/Troubleshooting may give a clue.
