Mozilla has released the *official* alpha of the next Firefox browser.

Called [Bon Echo](http://www.mozillazine.org/talkback.html?article=8146), it’s the first development milestone of Mozilla FireFox 2. Which means it’s early days and most people should wait for the full release. It’s really for developers and testers to provide early feedback and report bugs.

You can download it from [ftp.mozilla.org](http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/bonecho/alpha1/).

Here are the new features:

* Changes to tabbed browsing behavior.
* New data storage layer for bookmarks and history (using SQLlite).
* Extended search plugin format.
* Updates to the extension system to provide enhanced security and to allow for easier localization of extensions.
* Support for SVG text using svg:textPath.

Use with [caution](http://www.mozilla.org/projects/bonecho/releases/2.0a1.html). Remember, it’s really only for developers and testers. 🙂
