Mozilla has released the latest version of Firefox 4 Beta for both the Web and mobile phones (Android and Maemo). The desktop version offers easier account and new device setup for Firefox Sync Setup, Increased Support for 3D Graphics, Automatic Updates with new Firefox Add-ons Manager, and making Firefox Add-ons Compatible.
And, in the mobile version, probably the best feature is the ability to save any web page as a PDF, which is a handy way to read it later, especially if your connection goes down. On Android, you hit "Site Options" and then "Save as PDF." The page is then available in the downloads menu.
The new mobile version of FireFox also makes it simpler to sync bookmarks, tabs, and history with your desktop Firefox browser. And to minimize the need to type, it now supports cut-and-paste in the address bar.
