Mozilla has launched Firefox 4 app for Android, according to Los Angeles Times.

Users can sync their browsing history, bookmarks, tabs and passwords on every computer, smartphone and tablet they have as long as they have Firefox installed.

The Firefox 4 app can even launch websites on an Android device right where a user left off on the Firefox 4 browser at home. Mozilla has added plug-in "personas" that allow users to change the colors and even add images to the toolbars in the browser. It has twitter integration, tabbed browsing, search for text on a Web page and can save images from websites to a PDF format. Firefox 4 for Android is also available in more than 10 languages as of launch day.

Mozilla also released a Firefox app for Maemo on March 29. Maemo is a Linux-based open-source operating system for Nokia devices.
