Firefox on Android has supported Tablets for a while now but this release makes it official.
Mozilla spoke about the latest update:
Firefox for Android leverages large tablet screen sizes and optimizes popular features for tablets. The Awesome Screen integrates Firefox Sync and makes it easy to access your browsing history, open tabs, bookmarks and saved passwords across desktop and mobile devices so you can type less and browse more.
Tabs appear as thumbnails in the left panel so you can quickly switch between them while still viewing full websites on the right. You can swipe to the left to hide tabs for a full screen view.
Firefox optimizes your Web experience for both portrait and widescreen mode. In portrait mode, tabs are listed in a top left menu and easily hide when you don’t need them, allowing you to focus on the websites you visit.
With the new Action Bar menu (next to the Awesome Bar), you can access Firefox Preferences, Add-ons, downloads and more. The Action Bar adds the back, forward and bookmark buttons for easy access. One-touch bookmarks enable you to add an icon to your Android home screen for your favorite websites and Web apps, making Web apps as easy to use as native apps.
The browser supports a variety of new HTML5 technologies that would make development for this platform fun. Mozilla highlighted support for HTML5 Input Tag for Camera Access and HTML5 Form Validation API.
