There will be a fourth beta and it is expected quite soon. Probably by Febrary’s end. Release candidates could start by mid-March and hopefully on schedule for a first quarter final release.
Not much is left for the next beta: more theme retouches in all platforms, Vista icons, plus more retouches to Places and several other areas, some of them already available in the latest nightlies that followed Beta 3 freeze.
According to the latest meeting minutes, the revamped location bar’s autocomplete font size and colors could be reviewed to address some common complaints about it being too obtrusive. Support for multi-word searches is also planned, so for example entering star and then wii, will filter out starbucks while keeping that cool Super Mario Galaxy guide in the results.
Add-ons-wise, Firefox 3 support is moving fast and as much as 40% of the top extensions are keeping up with the betas and most likely to be ready by final release. This is at least in part thanks to a very early documentation process and a continuous call for developers. We could see an easy transition for the large number of users that rely on extensions and themes for their best web experience.
