Work on the Firefox mobile browser — aka Fennec — has been marching steadily ahead, and the team has released an official Alpha build. The highlights:

  • New Add-Ons Manager
  • New Downloads Manager
  • New CSS based theme
  • TraceMonkey, Mozilla's new JavaScript engine
  • jemalloc, the memory management library used by Mozillla.
  • Faster application start-up time
  • Faster panning
  • Faster zooming
  • Initial implementation of bookmark folders and bookmark editing

Just like with the pre-Alpha and nightly build versions, this was built and tested on an HTC Touch Pro, so there's where you're likely to have the most success. That said, this is Alpha, and bugs are likely.

Says Mozilla's Brad Lassey (read our interview with him here) in his blog:

It is not yet recommended to use this release for daily browsing tasks. Certain performance problems will become immediately apparent to the user. Panning has a noticeable delay between the user first touching the page and the page moving. We are certain that other less obvious bugs exist and we invite you to help bring them to light. You can find detailed information on how to file a good bug in bugzilla , our bug tracking system, here .

So remember, folks. This isn't a finished version, but a pretty big step in the process. Get your download on here (or here directly from your phone), and let us know in the comments how it works for you.
