I can watch certain videos on a channel just fine but some other videos on the same exact channel I can not watch. I get the following message:

Your browser does not currently recognize any of the video formats available.

When I click on the HTML5 I get the following:

What does this browser support?

HTMLVideoElement has a check next to it.

H.264 does not have a check next to it. It has a red box.

WebM VP8 has a check next to it.

Media Source Extensions has a check next to it.

MSE & H.264 does not have a check next to it. It has a red box.

MSE & WebM VP9 has a check next to it.


How do I get the 2 with the red boxes to have checks next to them??


I am using FireFox ESR 52.3.0 (32bit)

My os is Windows XP.

Firefox relies on built-in OS support to play media files via the HTML5 media player. On the Windows XP platform you do not have native support for playing MP4 files with the HTML5 media player.

You can try if the solution posted here to add support for playing MP4 files works for you.

This did not help me at all.
