Mountain View, California-based Mozilla Corp. has released the fifth beta build of Firefox 4 for Android and Nokia N900. Of course, the new build promises more stability and improved performance over previous releases.

In addition, Mozilla has released a version of the Fennec browser for Windows, Mac OS X, and even Linux to allow users to test the browser on their computers. As usual, the build comes pre-loaded with all of the goodness that one comes to expect from a Firefox browser such as add-ons, Firefox Sync, and more.
