Yup, that’s Firefox of the Linux variety, running on a Palm Pre. It’s the work of Dave Townsend, a developer for Mozilla that works on Firefox (among other open source projects). We don’t have much other info on it, but given the interface, we and Palm Developer Relations Team chief Dion Almaer came to a pretty easy conclusion about it: this is the kind of stuff you can do with the PDK. To quote Kool-Aid Man, OH YEAH!
UPDATE: Dave has posted a "how I did it" article on his blog. Instructions are absent, which is understandable given the hobby project not-even-in-alpha status of this project. All-in-all, it was about two days of work porting the Android project version of Firefox onto webOS, and it’s still buggy and the cramming of the Firefox UI onto the Pre’s screen isn’t exactly a great system. But it’s potential, and potential is something we’re rather fond of here.
Thanks to Bo for the tip!
Score another point for fast and easy development for webOS.
