Ever since the release of Firefox 3 we’ve been doing a lot of work to add new capabilities for web developers. We thought it would be worth it to make a post that actually listed all of the features that we knew about and people might not know about. This contains everything that we’ve done over the last three releases or so, but calls out stuff that’s new in 3.6.

Enjoy!
