Wow, I need a vacation. I apparently read this article and commented on it, and must have forgotten about doing either, as I commented on the followup article as if it were a new topic entirely. Still, Firefox extensions are cool and I want to get into writing them. I wonder if Greasemonkey can help plug the gaps between XUL and Hildon in any way? I know Greasemonkey isn't really for "plugins" per se, but it does give access to some of the Gecko API stuff, right?
