Firefox 4 for Mobile RC released, hints of new badge-collecting social game Firefox Spark
Moving away from the beta builds, this RC is more of a stability and spit-polish release than anything else. Usability-wise, the release notes point out that there are now 150 add-ons that work with Firefox 4 for Mobile, up from 100 last month -- and there's now a Form Assistant, which should make logging into websites a lot easier, especially if you have Firefox Sync enabled.
Finally, the RC contains a link to Firefox Spark, a new badge-collecting website, which seems to be one of Firefox 4 for Android's 'launch goodies.' As far as we know, Firefox Spark will be a social game, where you share the Firefox for Android download link, collect badges, and level up. We're not sure of the exact details yet, though.
Grab Firefox 4 for Android from the Market or download the Maemo version.
