There are some new features to tell you about as well.

• Per-tab private browsing: Private Browsing helps you control your personal data by letting you to browse the Web without saving any information about which sites and pages you’ve visited. With the latest enhancements to Firefox for Android, this (much-requested) feature allows you to switch between private and standard tabs within the same mobile browsing session, just like on your desktop. Private browsing data will not show up in your AwesomeBar History or Awesome Screen shortcuts. Learn more about Private browsing on Firefox for Android.
