Yes, John. Quite.
Firefox 56 was, if I'm not mistaken, the last version that did not use the Quantum
architecture. Many of us remember the upheaval the Quantum architecture caused. Mozilla
unilaterally yanked the rug out from under nearly every plug-in (as they used to be
called) & forced them to be rewritten. I delayed my own upgrade of Firefox for several
months while Michel scurried around getting VDH 7 to work in an adequate number of
situations. Quantum is the reason we now have a CoApp. The CoApp is new with VDH 7,
never having existed in prior versions. If you're on such an old release of Firefox, you
must be using VDH 6. There is no possibility you're going to get any support for that.
If you have somehow managed to install VDH 7.anything (I'm running 7.6.3a1 beta), then
you're still in an unsupported environment. Your complaints have fallen on deaf ears.
Nevertheless, Rokfin is a site unknown to me. So I went there & scrounged around. What
follows here is what you should have posted. It's called a proper problem report.
I'm on Windows 7 64-bit, Firefox 102 64-bit, licensed VDH 7.6.3a1 beta, CoApp 1.6.3. I
found this page:
https://rokfin.com/post/91405/Kyven-Gadson-Finishing-Touches-Off-Lat-Drop
It was something short (barely a minute long) & it didn't have a Premium flag on it.
When I went to the page, the video automatically started playing. I guess the site does
that. Annoying. I wasn't expecting that. If I had known that, I would have gone into
about:config & changed media.autoplay.blocking_policy from 1 to 2 before visiting the
site. I opened the VDH menu. It offered me 1 HLS variant. YouTube doesn't deal in HLS
content. I downloaded it. I got a 4.86M MP4 of duration 0:1:16, resolution 472x272. It
played perfectly fine in VLC.

There are many useful references in there, one of them describing how to make a proper
problem report. But everything is predicated on your getting on the current versions of
the software. If you refuse to get the current Firefox & the current VDH/CoApp, then
don't bother filing a problem report. In any case, my test shows there's absolutely
nothing wrong with VDH. It handles this site just fine, at least for free content.
Maybe the paid content is a problem. If anybody on the current software can post a
proper problem report about the paid content, we can discuss that. But for the time
being, this thread appears to be a dead end until you get on the latest versions of the
software.
