webOS still gets the short end of the third-party app stick more often than not for the simple reason that there aren't many devices in the field, relatively speaking -- and considering how late Mozilla is in the mobile browser game, they've got bigger fish to fry. Of course, the code underpinning Firefox is open source, so it comes as little surprise that it's been repackaged into a Pre-friendly form with the aptly-named PreFox. The app's developer warns that this is more of a proof of concept than anything else, but we're sure it could get whipped into shape with enough time and effort.
Separately, judging from a request for developers, Mozilla proper has started planning for a Symbian build of Firefox Home, its companion app to Firefox that makes transferring bookmarks and open tabs a breeze between your desktop and your phone. Seems like another case of attacking the low-hanging fruit -- Symbian's just about everywhere, and we're sure Mozilla would like to make its presence known.
