about:mozilla is a weekly round-up of news and contribution opportunities. Here’s what’s happening this week:

Firefox Affiliates
A new Firefox Affiliates site will be launching soon as a place for people to grab website buttons and promote Firefox downloads. Chelsea Novak wants your ideas about how to evolve the site and is setting up an IRC chat on Wednesday, August 10 at 6 p.m. Eastern in irc.mozilla.org#affiliates.

Cool Demos

Rob Hawkes shows how he built this WebGL and HTML5 audio visualiser demo. Check out more demo art and submit your own on the Demoparty site.

Building A Rainbow
Mozilla will be working with the Web Real-Time Communication project to create new JavaScript APIs for developers. The Rainbow add-on will be a way to experiment with real-time audio and video streaming, so give it a try and get in touch to help us mature this new technology.

Alert The Developer
Use the new Alert the Developer add-on to easily provide feedback about your favorite add-ons by tapping into Firefox’s current feedback system. This also gives developers a great way to get feedback from their users.

Let’s Talk Gecko
Mitchell Baker has a post about the importance of Gecko, the engine that powers Firefox, and how it helps advance Mozilla’s mission. Read more about how we can reach phones, tablets and other new devices by using Gecko either as part of Firefox or through all new user experiences.
