Thanks to another question of mine here on Superuser, I was pointed in the direction of XULRunner, which allows me to run Chatzilla without making having to install the addon for firefox: http://chatzilla.rdmsoft.com/xulrunner/

Which has the obvious benefit that I no longer face the problem that when I close Firefox, chatzilla closes too.

I'm wondering, are there more programs that run on XULRunner, that you use? Tell me about them.


A long but not complete list of applications on xulrunner can be found here


All Mozilla applications use XULRunner including Firefox, Thunderbird, Seamonkey, Sunbird. Some other popular applications are Songbird, Miro and Joost

There's a game based on XUL called Simon the Sorcerer 4: Chaos Happens

XUL based applications are cross-platform. The drawback being some of them might be slow on performance esp. start-up time can be a bit longer.

  • Yeah, but to run Chatzilla, I had to use the XULrunner.exe program to make it stand-alone.
