Firefox 13 Beta Available for Download
 

Not wasting much time following the Firefox 12 launch, Mozilla has now made available the public beta version of its next browser release. The Firefox 13 beta features an updated default home page (providing quicker access to bookmarks, history and settings), a tweaked new tab experience (users are presented with their most visited pages), smooth scrolling, the SPDY protocol which is enabled from the get-go, experimental support for ECMAScript 6 Map and Set objects, and a few more dev-oriented goodies.
