Without knowing what to look for, I'm lost. Lots of video stuff, maybe
100 codecs listed in about:config -- the only place I could find the
entire list.

Possibly, but I've been using this computer since 2011 (top-of-line at
the time with plenty of memory) with Firefox 6. Videos used to run with
no problems, but as I updated FF more and more things were lost. Not
sure when video problems started, but within the last two years, growing
worse when I upgraded from FF fortysomething to 52. At some point 52
got worser, with 57 playing some videos that 52 wouldn't. Now neither
will play ANY facebook video even when I had installed various
html5/flash extensions that claimed to deal with facebook videos.
SOMETHING is wrong, but the fact that Chrome works fine would seem to
indicate a software rather than a hardware problem. As previously noted,
the problem exists in new virgin profiles as well as safe mode. I
haven't added anything to /etc/hosts since April 2017, but problems
existed before that.
If nobody has an "AHA! I know exactly what's wrong!" solution, I suspect
it isn't worth spending time on. A lot of stuff doesn't work right with
slackware, most of which my live-in consultant is NOT interested in
dealing with. He LIKES Chrome :-(
