There will be progress updates on the various active Labs projects as well as plenty of opportunity for discussion and hacking. And, of course, pizza. If you are in the Bay Area, we’d love to see you!” If you’re planning to attend, please take a moment to RSVP by commenting on the Mozilla Labs weblog.

Extend Firefox 3 — the contest in which participants submitted new or updated add-ons for the Firefox 3 web browser — has wrapped up and the winners have now been announced. Many of the contest-winning add-ons are in the early stages of experimental development, but they are all powerful new tools and prototypes that the judges felt were worthy of recognition. For the list of winners and further details about the contest, please see the Mozilla Labs weblog.
