Mozilla's 10th anniversary party at 111 Minna last night felt a little like a high school reunion for the kids who didn't go to their high school reunion. The Mozilla Foundation, maker of the Firefox browser, feigned poverty by renting just half the gallery space and serving up crudités and issuing one drink ticket per guest, only later splurging by opening up the bar. There was some awkward dancing to Soft Cell's "Tainted Love," old jean jackets embroidered with the Netscape logo, a gargantuan chocolate cake and a photo booth. Many of the oldsters who were around when CSS was just a dream and Ajax was still used to scrub toilets also traded reminiscences of Burning Man, tech society's annual prom. Mozilla Foundation chair Mitchell Baker earned part of her $500,000 salary by giving a brief speech. And sign-toter Frank Chu showed up, uninvited but always welcome. But the talk of the party was the man who wasn't there.

That was Jamie Zawinski, the Netscape engineer who helped "free the lizard" by open-sourcing Mozilla, even though he apparently offered up his SoMa nightclub, DNA Lounge, for the event. Zawinski did, however, build a time capsule of the early Web — including early iterations of the Mosaic browser and website — for those of you who couldn't make the party but would like to wallow in the nostalgia. Who did show up? Dozens who RSVP'd after Valleywag's calendar listing yesterday, forcing Mozilla to open up the bar when the drink tickets ran out.
