Xul

Mozdev and Mozilla Europe have teamed up to create a Firefox Mobile (Fennec) Add-ons Challenge. The goal is to create or port add-ons to Fennec. You only need to propose a concept for now, but you’ll need to get the add-on ready for the upcoming Mozilla/Maemo developer weekend in Copenhagen on May 30-31.

While I was on vacation last week, the newest official XULRunner was spun up and has now been released. XULRunner 1.9.0.7 matches the Firefox 3.0.7 release. For XULRunner developers, most of the changes in 1.9.0.7 are related to security fixes. There are some cookie and XHR fixes in there too. You can also look at the full list of fixed bugs.

The newest official XULRunner has been released. XULRunner 1.9.0.6 matches the Firefox 3.0.6 release. For XULRunner developers, most of the changes in 1.9.0.6 are related to security fixes. You can also look at the full list of fixed bugs.

FOSDEM 2009 is over. Once again, there was a lot of great stuff happening. I managed to leave the Mozilla Room once or twice to see other sessions. The Mozilla Room sessions were very good and not just because I was in two of them. There were so many people trying to get into the Mozilla Room, we had to stop people from coming in.

It’s taking a while to get nightly XULRunner 1.9.1 builds available. At this point, I’d like to have nightly XULRunner 1.9.2 builds available too. In order to help anyone that really wants to start building against XULRunner 1.9.1, I made some unofficial runtime and SDK builds.

Fennec Alpha 2 is now available for download! Desktop versions are available too (Windows, OS X, Linux). While we added some good features in this alpha, the primary focus was performance. Faster startup. Faster page loading. Faster panning and UI interactions.

I decided to take a detour in my XULRunner session at MozCamp. I have done several XULRunner talks over the last few years. I usually focus on the functionality built into the platform and discuss the benefits of using Mozilla technologies to develop applications.
