On some platforms Firefox doesn't include h264 support due to licensing, and you have to install it manually. But this is the first time I've ever seen that on Windows.
I would suggest updating Firefox. If the issue persists after that, try resetting the browser to default settings, removing any extensions, etc.
tried the browser without the extensions, no go. interestingly enough it did work on another workstation of mine with firefox and all the extensions enabled... so it wasn't the browser or the extensions.
and after a few more media sites break (youtube and spotify), firefox came to the rescue by showing me a help file that suggested installing the Media Feature Pack. yes, that simple. turns out am running an N version so i just needed to install the Media Pack Feature via Settings>Apps and feature>Optional features then reboot.
apologies for the fuss caused. and now back to my videos.Go to the full post
