Facebook videos still won't play

.....as usual.  Haven't played since FF52.  I just downloaded the latest 
(FF61) version for linux, made NO personalizations, used the profile it 
created, and got the usual non-result:  click on the 'play' arrow and 
nothing happens.  Sometimes the "Something went wrong" FB message with 
useless suggestions pops up.  Sometimes no error message, nothing, just 
a screen reload.

No problems with Chrome, which I despise

It's been suggested that various extensions, settings,  .css file 
entries etc. caused problems, so I did NOTHING.  Just started FF, opened 
FB, logged in, hunted for a video that I know plays with Chrome, and 
NOTHING.  Tried several videos.  Same thing.

I absolutely guarantee that I've done nothing to this version except add 
my FB password.

What parts of ffmpeg and/or h264 libs have you got installed?

Slackware 14.2

-rw-r--r--   1 root 4527751 Nov 21  2011 ffmpeg-0.8.7.tar.bz2
-rwxr-xr-x   1 1016    4437 Dec 18  2011 ffmpeg.SlackBuild*

/usr/lib64/opera/libffmpeg.so
/usr/share/skypeforlinux/libffmpeg.so

What else should I look for?

Lots of h264 stuff.  What specifically?

Youtube videos MOSTLY don't work.  Some news videos work, some don't.

Everything worked fine up until FF52.  Chrome still works.  Opera 
installed a year ago works.  Mplayer works.

What does FF do differently now (next version of FF that I ran was 57; 
I don't know if the change occurred earlier)  that needs new/more stuff? 
  If it needs something, why doesn't it tell me what it wants? 
Something is clearly missing, but I've already done a lot of what 
amounts to guesswork and flailing and this just shouldn't be necessary. 
  A lot of libs come with FF, why not EVERYTHING it needs?

gstreamer and its good/bad/**** plugins?

that would be about all that I had to install last time I did a fedora 
install from scratch to get firefox working with youtube, vimeo and BBC 
iPlayer, which is about all I need ...

I've got tons of that too.  Whatever gets automatically installed with 
slack 14.2

  It would be nice if the mozilla people would tell us what's 
missing rather than making us guess.   And guess wrong :-(

Me too. I am currently running firefox-60.1.0-6.el6.x86_64 on
Red Hat Enterprise Linux Server release 6.10 (Santiago)

And if I try to download the thing, Firefox just crashes.
