Mozilla celebrates the 6th anniversary of the release of Firefox (Firefox 1.0) on November 9th. Mozilla is inviting people to join in the celebration,

This year, to celebrate Firefox and the Mozilla community’s work promoting innovation, choice and openness on the Web, we ask for your help to showcase how people love and use Firefox in your part of the world. Just send us a postcard with your message about Firefox and your FoxCard will be featured in our Mountain View or Paris offices. You can even win Firefox goodies when you send in your FoxCard. Check out our FoxCards page on Facebook or Spread Firefox for more information.

Also Mozilla is asking for people to help test Firefox 4 Beta. You can read more and see a ‘cool’ photo from the Mozilla Summit 2010 this past July in Whistler, BC, Canada at The Mozilla Blog.
