I started building my first Firefox extension last night and as a result I had to dig into XUL (pronounced zool, al la Ghostbusters).
Now I have been aware of XUL for years but haven’t really thought about it much until I clicked on the XUL Periodic Table example that I suddenly realized that XUL makes for a pretty swanky RIA platform (not too mention it was around years before the others).
Of course if you clicked on that XUL Periodic table example above using Internet Explorer then of course it would not have worked since IE doesn’t support XUL which of course is a bit of a problem.
I wonder how hard it would be to get the XUL engine installed as an IE helper application for .xul files? Maybe something else for me to play with :)
