URL (and Title) from Firefox (subroutine)

I knew I'd got that idea from reading a post here and yes, it's near the top here: Get the Browser Page Title & URL for Safari, Chrome, or FireFox
It doesn't look as though the macro there actually uses that technique for some reason.

I don't understand that... The action uses Cmd-I as written, and I've just downloaded and imported the copy posted here, and it still says Cmd-I! Anyway, that's what's needed!
ffff
