In case you hadn’t heard Mozilla are running a developer day in a week or so’s time in Toronto. The first day is aimed at giving a good overview of the Mozilla platform and what technologies it offers. The second day will be a more hands on workshop where you can try your hand at extensions, applications and testing with friendly experienced people around to lend a hand when you hit problems. It isn’t far off now so get yourself signed up if you’re coming.
I’m in the midst of trying to put together what I’ll be talking about so if you have anything you particularly want to hear then make a suggestion.
