Mozilla just released their final version of Firefox 4 Mobile Browser fr Android and Meamo. Its available at the Android Market and you should definitely give it a go.

The new Browser brings Tabbed Browsing, Firefox Sync, Add-ons and major speed improvements. Firefox Sync lets you easily sync all your passwords, history, bookmarks, and even the tabs open in your PC even if you are a mile away. Firefox still does not have full Adobe Flash support but is speedy compared to other browsers.

Firefox uses some simple gestures for accessing tabbed windows, bookmarks and history etc. Swiping left lets reveals the forward/back buttons and also an option to add the page you are on as a bookmark on the right side. Swiping right brings the current tabs on the left side. Pinch=Zooming is not as good as in the Android Browser, but tap-hold options are added for opening a link in new tab, or saving/sharing it. Scrolling on a page is smoother than ever and browsing is super fast.

Get it on the Android Market but make sure that the update might not yet be available in all countries.
