Tired of using the default browser on your smart phone to browse Engadget? Got a thing forFirefox? Great, 'cause Mozilla just pushed out the fifth beta of Firefox 4 for mobile. You might be familiar with the on-the-go version of Mozilla's creation, but if not, here's your chance to grab the latest (and probably) the most stable build to date. In addition to the Android and Maemo version, the company has released a Fennec build for use on Windows, OS X and Linux.
We tinkered with the OS X build of the browser on our Macbook Pro and although pages appear to render quickly, we can't quite figure out how to navigate backwards. You can pinch-to-zoom with the trackpad and scroll with the d-pad, but once you've loaded a page, it seems you need to be on a mobile device do any further navigation. Of course, as you'll see in the gallery below, the beta comes packed with the usual -- preferences, downloads, add-ons, bookmarks and Firefox Sync. If you want to give the software a whirl, hit the source link to grab the build of your choice.
