Just days after releasing Firefox 12 with silent updates and 85 improvements, Mozilla has unveiled a beta version of Firefox 13. "The updated browser comes with three major redesigns. Mozilla has redesigned the Home Page, which now gives easy access to Bookmarks, History, Settings, Add-ons, Downloads and Sync Preferences with one-click shortcuts. It also offers a redesigned New Tab page which allows you to open a new tab, get to your most recently and frequently visited sites, customize, add or remove thumbnails to get to where you want to go in one click," says the post on Mozilla's official blog.

"The new Tabs on Demand feature loads tabs on demand when you restore a previous session, which makes it faster to restart Firefox windows with many tabs,” the blog post adds.

Firefox 13 Beta is now available for download on Windows, Mac OS X and Linux.
