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

New Features, Less Interruption For You On The Web
Private browsing window
During the last weeks, thousands of Mozillians have coded and tested the next version of Firefox to a fare-thee-well. A few days ago, we were proud to finally release Firefox 20, in which we have fixed about 300 bugs. But we also added new features: You can now open Private Windows that allow you to surf the web without saving any information about which pages you’ve visited. We have also added a new download button to your toolbar. Last but not least, Firefox is now able to open PDF files directly without using a plugin like Reader.

Find out more about the new features.

Samsung, Mozilla And Our Browser Engine
Firefox is already fast by default, but at Mozilla Research, we want to make it even faster by experimenting with what’s next when it comes to the core technology powering the Web browser. Since we need to take advantage of tomorrow’s faster computing architectures, we’ve recently teamed up with Samsung on an advanced technology Web browser engine that is called Servo. This program is basically a clone of Firefox that has been built from the ground up on modern hardware. It’s been written in a language that prevents entire classes of errors that lead to crashes and security vulnerabilities.

Public Mozillians Profile Mozillians.org is our community directory that our core contributors use to find and contact each other. Several of you have asked us for an option to share their profiles with other people who aren’t registered and we’ve listened to them: From now on, you can also display your profile publicly by using the new privacy controls. You can choose which information you want to be on your publicly viewable profile. If you want your profile to remain visible to only Mozillians, you do not need to make any changes.

Read William Reynolds blog post, in which he explains how to change the visibility for your profile.

Preparing for the Next Chapter
When Gary Kovacs became the CEO of Mozilla in 2010, he joined us to make a dramatic pivot – to move Mozilla from the desktop browser world into the mobile ecosystem with Firefox for Android and Firefox OS. We have accomplished so many things since Gary joined us. Last Wednesday, Mitchell Baker, Chair of the Mozilla Foundation, announced that he will step down as CEO later this year. This is the perfect time to thank him for his contributions to our cause, and for bringing new things to Mozilla.

Thoughts on Mozilla Research
Brendan Eich, inventor of the JavaScript language, gave a brief talk at the Mozilla Research Party, which happened to fall on the celebration of Mozilla’s 15th anniversary. In his talk, he talked about his memories, but also about his thoughts on Mozilla Research. He started off by stating the main problem: Software, especially “in the large”, remains quite challenging. In his opinion, calling software an art should not relieve us from advancing computer science. In the past, we already found that out: Because code kind of rusts over time, Brendan declared it time to rebuild major parts of the code back in 1998. Today, he designates this near-total rewrite as a big mistake.

Find out how this mistake hurt Netscape but helped Mozilla, Firefox’s predecessors.

Mozilla Summit 2013
Every once in the while, the core contributors of Mozilla from all around the world get together in one place. This is called the Summit. This year, we’re doing something different: We want to have three locations with up to 700 people, some shared content and some innovative ways to join the three locales. If you’re a registered Mozillian, you have already received an e-mail with instructions on how to be considered for an invitation. Till the deadline on the 17th of April, you can still apply for an invitation that will be sent out in May.
