Firefox for Android has not supported the very old Flash Player 11.1.x from Adobe since 55.0 as 56.0 and later dropped it.

So I wonder if they are serving a HTML5 player to Android Firefox but not to desktop Firefox?

Seems that they use HTML5 to Android Firefox. I found extensions called user agent switcher or similar names that make desktop Firefox pretend to be Android. The news live stream still cannot be played in Firefox, but I can right click on the video, copy the address of the m3u8 file and use mpv to play it for about five minutes.

Do you get all checks as blue on https://www.youtube.com/html5/ in desktop Firefox? and can you play test videos at https://www.quirksmode.org/html5/tests/video.html

If a couple are red on above youtube page then perhaps you do not have packages like FFmpeg installed in your distro package manager.

I get all six checks as blue on https://www.youtube.com/html5/ in desktop Firefox and I can play all three test videos at https://www.quirksmode.org/html5/tests/video.html. I am using Manjaro Linux, and ffmpeg is a dependency of firefox. I also tried installing firefox2.8, but I still cannot play it.

With a mobile user agent I get this error message in the Web Console:

HTTP “Content-Type” of “video/mpegurl” is not supported. Load of media resource http://cctvs.cntv.dnion.com/live/no/24_/seg0/index.m3u8?<GET parameters> failed.

Seems that Firefox for Android also plays for only about five minutes, so maybe the website is at fault.

I just tried using flash again, and the site could play news. I am not sure whether it is related to update or the site changed the way the play on desktop.
