Hi Kris, That looks really neat and a nice step forward! I’m a fan of all the things you’re doing, btw ;-)
Whilst reading through the docs you pointed at, I was missing a few things, to be honest: * Perhaps a link (or multiple links) to MDN docs we already have on XPCOM components - which may provide an introduction as to what they are, when and why they’re used, etc. * An example of ‘old style’ vs. ’new style’ xpcom definition, perhaps even a ‘good’ vs. ‘bad’ - but there’s a negative connotation there, which may not be preferred. * A full example (prolly on a second page would be best), which showcases the discrete steps to get from zero to hero. Err, I mean new component. I’m suggesting all this extra work, because I think it will actually save you a lot in the future; rtfm is a very simple, yet powerful response to all the queries you’re gonna get.
