Firefox 19 was released released less than a week ago, but already Mozilla has made a new Firefox for Android beta available. This new release adds per-tab private browsing, customizable home screen shortcuts, and support for 25 million more phones.

Per-tab private browsing is of course the biggest new feature. It allows you to switch between private and standard tabs within the same browsing session, meaning you don’t have to relaunch the Firefox app every time.

For those who don’t know, private browsing lets you browse the Internet without saving any information about which sites and pages you’ve visited (private browsing data does not show up in your AwesomeBar History or Awesome Screen shortcuts). Other browsers have it too, and is often referred to as “porn mode.”

Customizable shortcuts on the home screen are pretty straightforward. You can now customize the shortcut images on the home screen with your favorite or most frequently visited sites by simply tapping and holding your top sites, and then choosing “pin” from the drop-down menu.

Last but not least, Mozilla is continuing to expand its ARMv6 support. Firefox 19 added support for 15 million more phones and now this beta is adding support for yet another 25 million. This is thanks to the minimum requirements of 600MHz, 384MB, and QVGA. The following devices are now supported as a result: Samsung Galaxy Next (GT-S5570, GT-S5578), HTC Aria (S31HT), HTC Legend (A6363), Samsung Dart (SGH-T499), Samsung Galaxy Pop (SCH-i559), and Samsung Galaxy Q (SGH-T589).
