The new "Share" button lets users post an interesting article to friends and family via profile, private message, or e-mail, without having to leave the page. This is already complemented by a slew of recent feature add-ons in Firefox that include the ability to view your feeds, check status updates and activity, and chat with friends directly within the sidebar.
Mixed content blocking is now also enabled by default to provide greater protection against "man-in-the-middle" attacks and gives users more control over what types of content can be loaded.
Firefox for Android also comes with a new update. Updates include the "Awesome screen," a bookmark screen with direct links to saved pages, much like the "Speed Dial" page or bookmarks page found in Opera and Chrome, respectively. Yes, you read that correctly..."Awesome screen."
A more notable upgrade is what Mozilla has done with the title bar, itself, as well as a new "Switch to Tab" function. The title bar will now attempt to automatically predict and fill in the URL of the site you're trying to reach, similar to the Omnibar functionality found in Chrome. When not in use, the title bar will automatically slide out of view, giving you more screen estate to view your content.
Switch to Tab lets you quickly visit bookmarks saved in your "Awesome Screen" directly within your active browsing tab, without the need to open new ones, and reducing clutter in the process.
And, of course, there's the complimentary RSS feed reader; you can now subscribe to RSS feeds simply by long tapping and holding the "Awesome Bar."
