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.

One of the opportunities I had at MozCamp was to get caught up on the stuff happening in Thunderbird & Calendar. They have a goldmine of great data, functionality and UX possibilities. During some of the sessions and a small ad-hoc discussion, the use of HTML in XUL to create compelling, interesting and useful user interfaces came up. Thunderbird 3 will be using HTML to enhance to appearance and functionality of message display. Calendar might be using HTML to do the same for displaying tasks, IIRC. The examples I saw looked great.

Last night, support for Fennec on AMO was pushed live. A big thank you to Mike Morgan and crew for making this happen. There are no recommended Fennec add-ons yet, so you need to search for them. Here are some results, based on the two add-ons I know support Fennec and are on AMO:

Okay, so it’s only two add-ons, but it’s a start. First, MR Tech’s Local Install from Mel Reyes was updated with support for Fennec. Then, URL Fixer from Chris Finke got support for Fennec.

Some of the feedback we received from Fennec Alpha 1 (and we have received a lot, thank you!) has been about the download and “on disk” size. Fennec is based on XULRunner, Mozilla’s runtime platform. Therefore, when you install Fennec, you’re installing the XULRunner dependency too. Fennec is ~ 1MB in footprint size, while XULRunner is ~ 25MB.

I am headed to Barcelona to take part in Mozilla Europe’s MozCamp 2008 conference. I’ll be presenting sessions on XULRunner, Fennec Add-ons & Embedding Gecko. If you’re interested in any of these sessions and have topics you’d like to see covered, let me know. Commenting here or adding items to the wiki pages are goods ways to do that.

XUL Explorer is a small tool I started a while ago to allow me to quickly create and preview short snippets of XUL. At the same time, I used the process of building XUL Explorer as a use case to help me discover and learn various parts of the Mozilla platform. With the help of some great contributors, it’s been extended beyond simply previewing XUL.
