The engine/fuel terminology is not new, it comes from the 1986 paper "Abstracting Timed Preemption with Engines" / Christopher T. Haynes, Daniel P. Friedman:

@dang, here's an updated version of valid-url which will make the link clickable:
(defmemo valid-url (url)
(and (len> url 10)
(or (begins url "http://")
(begins url "https://")
(begins url "ftp://"))
(~find [in _ #\< #\> #\" #\'] url)))
It looks like the other change necessary is in the `markdown` function. It checks:
(and (or (litmatch "http://" s i)
(litmatch "https://" s i)
(litmatch "ftp://" s i)
Of course, the cost-benefit doesn't quite add up here – it's not like ftp links are too common. But think of the poor university FTP servers! They'll be forever doomed to copy-paste-hell unless this is fixed. :-(
Maybe it was removed for the Windows build? If so, what a bad decision, maybe for security reasons?
I normally use FF Nightly which explains the difference.
That might sound crazy (FTP is an ancient protocol), but I spend a lot of time scouring FTP servers for old technical reports. Mozilla can't just wish FTP away.

Not sure what arcs support for regular languages is like.
It certainly is, at least on Firefox 80.
