Firefox 15 hasn't been out for very long, and yet Mozilla found the time to release beta versions of Firefox 16 for both the desktop and Android devices. There is not much to talk about when it comes to Firefox 16 beta for Windows, Mac and Linux, since the changes there are mainly for developers. The big changes however, comes in Firefox 16 beta for Android; fans of Mozilla's mobile browser should be happy with what the company has been doing in this version of Firefox for Android.

Firefox 16 beta for Windows, Mac, and Linux features:

• Developer Toolbar: Firefox Beta introduces a new way to access Firefox Developer Tools. Selecting "Developer Toolbar" on the Web Developer menu of your Firefox toolbar will bring up a bar at the bottom of the screen that provides quick and easy access to all the Firefox Developer Tools. A unique-to-Firefox command line allows you to rapidly control your tools without removing your hands from the keyboard.

• Unprefixing of Stable CSS4 Features: Developers no longer need to add vendor prefixes for CSS3 Animations, Transitions, Transforms, Image Values, Values & Units and IndexedDB. Firefox Beta also unprefixes Battery API and Vibration API, two Web APIs that Mozilla helped create.

Firefox 16 beta for Android features:

• Reader Mode: Firefox for Android Beta makes it easier to view and read Web site articles with Reader Mode. When viewing articles and stories on text-heavy pages like news sites and blogs, tapping the "Reader" icon in the Awesome Bar will activate Reader Mode. Reader Mode removes advertisements, reformats pictures and increases font size to show a clearer view of what you're reading. Reader Mode also lets you share the pages you are reading over Bluetooth, email and SMS with the Share button on the bottom right of the screen.
