State of the Internet report
Last week the Mozilla Metrics team released the first ever Mozilla Quarterly Analyst Report, focusing on the State of the Internet. “This is the start of something new…in addition to metrics related discussions on this blog and across the broader community, we wanted to create a somewhat standardized, ongoing report capturing the state of the internet as seen through Mozilla’s eyes. You should expect to see this report released at the end of each calendar quarter.” Read more about the State of the Internet report and download the PDF on the Metrics weblog.

Create the Official Mozilla 2010 t-shirt!
The Creative Collective’s Mozilla 2010 T-shirt design challenge has been running for a couple of weeks now, with the final deadline for submissions on Apr 30th. John Slater has posted some great tips for creating the “Most Awesome Mozilla T-shirt Ever”, including: 1) you don’t have to use the dino head; 2) If you must use the dino head, do it in an interesting way; 3) Avoid text; 4) Remember that the challenge is about Mozilla, not Firefox (or any other specific product); and 5) Abstract is better than literal. John’s post discusses each of these points in detail, so if you’re thinking about submitting a design, it’s worth a read.

Firefox and page load speed
“By making a few minor tweaks to our top landing pages, we can drive an additional 60,000,000 Firefox downloads per year. What are the tweaks? It comes down to just one factor — speed. As it stands, our landing pages can be painfully slow. After implementing changes in an A/B test, we saw impressive results. Our optimized experimental variation shaved 2.2 seconds off the average page load time and increased download conversions by 15.4%.” Read more details about this optimization project and its results at the Blog of Metrics.

Big week for Gecko
Robert O’Callahan jotted a quick note summarizing some major development milestones the platform team has recently hit. “Bas Schouten landed his OpenGL layers backend and we’re using it to accelerate full-screen video on Windows. David Baron landed his fixes to the :visited privacy leak. Chris Pearce landed the new Ogg decoder to get rid of some nasty problems and make forward progress faster. Josh Aas turned on out-of-process plugins for Mac.”

Add-ons review policy changes
Jorge Villalobos has written about some recent modifications to the Add-ons site review policies. The policy page itself won’t be updated until the next AMO release, expected sometime in mid April, but most of the policy changes are already in effect and the AMO Editor team is making sure they are followed. Jorge goes through the changes point-by-point in his write up, with links to more information.

Thunderbird feedback wanted
Blake Winton writes, “For the next version of Thunderbird, Bryan Clark, Andreas Nilsson, and I have done a lot of work to make it easier to upgrade your profile from Thunderbird 2, and we would like to hear what you think of it and how we can make it even better.” Recent builds include these changes and can be downloaded for all platforms though links provided on the original post. The team is looking for feedback as soon as possible, and ask that you leave your feedback on their GetSatisfaction topic by the end of the day on Wednesday (Apr 7).

Add-ons manager redesign update
The Add-ons manager redesign continues apace, and Jennifer Boriss has posted another update about recent progress. “The biggest change you’ll see is that the add-ons manager will no longer appear in a separate window, but in a tab in Firefox’s content space. This represents a big shift in Firefox’s interaction model. Eventually, we’d like to move many of Firefox’s ‘extra’ windows (Download Manager, Bookmarks, Library, etc) into the content area. The add-ons manager, by being the first, will hopefully provide a solid working model that will guide the redesign and improvement of Firefox’s other windows.” Boriss’ post goes on to discuss other aspects of the redesign, including icons, the “extra” windows model, and various design influences that have factored into the project.

SUMO platform roadmap
The Firefox Support team is working on a new platform (codenamed Kitsune) for the SUMO project, and recently posted an update regarding their 2010 milestones and priorities. “Since development resources are limited and a project like this requires that we scrutinize our priorities, we’d like to make it clear that we will devote as much time as possible to Kitsune development. As a result, any work on the previous (Tiki) code will be strictly for maintenance purposes: unless a bug in the previous code simply must be fixed as soon as possible, it will likely not be worked on.” Some changes have also been made to the planned SUMO milestones, which Chris Ilias has outlined in his post.

XUL school tutorial
The Mozilla Developer Center is now home to a new add-ons development tutorial. “The XUL School project was developed by Glaxstar (now Appcoast) as a comprehensive extension development tutorial, covering the most significant aspects of extension development, including proven techniques and high quality standards.” The tutorial covers a wide range of topics, from getting started with Firefox extensions through adding menus and toolbars, to JavaScript Object management and handling preferences.

Drumbeat project update
“Since my last update, we’ve launched a developer version of and held two community events. Also, two of our bootstrap projects have moved beyond planning into roll out — P2PU Open Web is running its first course and Web Made Movies has started shooting.” Mark’s post has lots more information about what the Drumbeat project has been up to, including some highlights, notes about where they need help, and quick updates about projects, events, and the website.

MDN survey reminder
Erica Jostedt writes, “Last week, the Mozilla Developer Network launched the second quarterly survey to obtain developer feedback. Also on are results from the first quarterly developer survey conducted in November. Thanks to the feedback from more than 5,000 developers, the Mozilla Developer Network was able to put in place a solid plan. We would appreciate your feedback and help to get the word out about our new survey.”
