a series of updates on what's coming in Firefox 4

Over the next couple of weeks, people like Paul Rouget and I are going to post a series of updates on a bunch of technologies that are part of our next release. That release, likely called Firefox 4, was underway before the release of Firefox 3.6 and already includes a bunch of new features, bug fixes and performance enhancements. (As an aside, I personally suspect that in a lot of ways Firefox 4 is likely to be a revolutionary release for both users and web developers, but more on that in later posts.)

Since we’re in the middle of the development cycle it’s important for web developers to know what’s coming and how they can test them. We’ll talk candidly about not only what’s coming, but why they are important. Very often in the current race to improve browsers context is lost on why something is or isn’t included, or why something is higher priority than something else. We’ll try and shine some context on a lot of these things as well as give good technical info about our roadmap to the next Firefox release.

So stay tuned, it’s going to be a fun ride.

    Beta schedule is still in flux right now, but I think we’ll be to beta quality in the next few months. I think the beta cycle might be long, but it’s hard to say at this point. The future is hard to predict. :)

    Do I understand correctly that Firefox 4.0 is going to supersede Firefox 3.6, so no Firefox 3.7 release in-between? (or in other words: current 3.7 is to become 4.0?)

    I wonder if Brendan’s Roadmap Updates will ever get, you know, an update. The last post there was in 2008…
