Mozilla has released Firefox 4 for Android and Maemo. You can get the new version from the Android Market to test on your Android device or go to to get it in on your Nokia Maemo device. The final build is available in more than 10 languages on a list of supported devices.

Mozilla boasts that Firefox is up to three times faster than the stock browser on Android. For a more detailed overview of these claims, check out Firefox for Mobile Performance Overview by Mozilla developer Brad Lassey.

Mozilla released a Firefox 4 beta for Android and Maemo last month followed by Firefox 4 Release Candidate for Android and Maemo earlier this month. Once the desktop version was out, it looks like Mozilla was able to push out the mobile version very quickly. Hopefully this will be a trend with future versions of Firefox.

"Firefox for mobile allows users to take the Firefox experience they love everywhere and minimizes typing with features like tabbed browsing, bookmarks, add-ons and Firefox Sync," a Mozilla spokesperson said in a statement. "With a sleek new look that hides browser controls when not in use, Firefox allows users to focus on the websites they visit. Firefox Sync gives users seamless access to their browsing history, bookmarks, open tabs, form data and passwords across computers and mobile devices. Firefox also offers thousands of ways to customize the features, functionality and look of mobile Web browsing with Firefox Add-ons."
