Why are video downloader add-ons so popular?

there is probably an element of user education as part of this
investigation and fix.

I'm guessing a lot of this video download content is porn, and there might
be quite
a bit of phishing going on with offers to "get these videos
with our special video downloading sofware..."

the special video downloading software doesn't actually have to do anything
better, but the user thinks they might be getting additional value.

once the user buys into that its easy to get extra software on their system
that can be monetized in several different ways, with adware, malware,

An independent research study with lots of press around if all these
are actually helpful in improving performance might be the place to start.

If we could say definitively and universally say that the downloaders
actually offer
no perf gains, and they open up the door to a lot of risks that would be
a great message to send and have echoed to users of all browsers.
We might need product work to get there.

It would also be a good step to validate any claims made by
downloaders offered off of amo and sites where we have control
over the content that promotes the downloader addons.
