All users subscribed to AMO beta channel will be automatically updated. See the Development Channel section at the bottom of the page.
The main new feature we have introduced in this release is called Closure Inspector. It’s been previously implemented as an extension (FireClosure), but is now integral part of Firebug. So, you should uninstall the extension if you have it in your Firefox.
Please post feedback in the newsgroup, thanks!
