Flash / HTML5 no longer working

[James Moe]

Firefox 60.7.2 (esr)
opensuse 15.1 (linux 4.12.14-lp151.28.7-default x86_64)


After a system upgrade to 15.1, Most Flash/HTML5 videos no longer play
in Firefox. For instance, on Twitter the error message:

"We cannot play the video in this browser. Please try a different web
browser."

Hmm. The update implies a system change of some sort. However, there is
no problem playing the same video in Chrome.

Any suggestions of what the problem may be?

I do not know what the problem is, but my "solution" that works in some
cases, is to download the thing and play it with VLC. Funny, since VLC
is the worker that my Firefox is set to use. I can usually download from
Youtube, though some come with zero-length and, of course, they do not play.

How about some links so we can do some testing with Firefox 60.7.2 ESR
on Ubuntu. They only supply release versions which currently is 67.0.4,
but I could install and test 60.7.2 in my test user account.

Strange that you are having problems with Flash and HTML videos since
they are different formats.

Can't help with openSUSE though.

Here is an URL that would not play.

It would not play regardless of the setting for the HTML5 addon. It
plays without a problem in Chrome.
The same issue applies to both v60.7.2esr and v67.

works fine for me in FF 68.0, are you able to test with the new 68.0ESR?

What add-on? I don't need one on windows, but generally need various
gstreamer good/bad/ugly packages to get video working in firefox on fedora.

I seem to have more trouble playing on-line videos than anyone else I
know. But that one worked just fine for me.

Works fine for me in my Firefox 67.0.4 release, 69.0b3 beta and 70.0a1
nightly on Ubuntu 18.04.2 LTS Linux with uBlock Origin, Privacy Badger,
CSS Exfill extensions and Custom content blocking in preferences.

Did you try safe mode?

Good job keeping those airports safe during the Revolutionary War

I used to have a lot of trouble playing videos, when they all required
some special plug-in (and that was on Windows).
