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

Attention Photographers: Firefox OS Needs Your Help
The Firefox OS team is looking for phone wallpapers for B2G. Every smart phone has a set of default wallpapers that play an important role in setting the tone for how both the brand and product are perceived. For the press or for marketing campaigns, featuring screen shots of the product is also important so that people can see what it’s all about – and about 10 photos of real people that can be used in these screenshots are needed too. Read about how to submit your photos.

National flag collection

Customize Firefox with your nation’s flag and join us in celebrating the spirit of community that’s bringing the world together this month — just like Firefox does all year long. See the complete theme collection and cheer on your nation.

A Cat Signal in San Francisco
A few days ago, you might have seen something interesting in a certain area of San Francisco – a large cat that was projected onto several buildings from the roof of the San Francisco office. However, this wasn’t a marketing campaign for over-sized lightbulbs, but it marked the official launch of the Internet Defense League. The cat was a symbolic way to bring together people from across the web to defend the open internet and push to make it better. On the “Engaging Openly” blog, you can find out how to sign up as a member of the league.

JavaScript Terminal in Firefox
Paul Rouget, a Mozillian since 2003 and a passionate Developer Tools team member, created an experimental restartless addon called “JSTerm”. It adds a terminal that acts just like a regular shell terminal, uses the builtin Firefox Source Editor to highlight JavaScript code and a Sandbox to eval it. If you are a website developer, you might also be happy to hear that it comes with an Object Inspector. Read his blog post to see why it was created — although there are already similar tools in Firefox — and how you can use it.

Building Community around Webmaker Tools
Matt Thompson, Chief Storyteller of Mozilla, asks an interesting question in his latest blog post: How do we grow a community of contributors and architecture of participation around Mozilla Webmaker tools? This was discussed by the Webmaker community during a weekly call and the answers to this question are great. It was decided to make contribution the metric that defines all our work and to build better on-ramps for participation. Read his blog post to see all of the ideas and to read the four keys to involving contributors.
