What can XUL do?
¥Extensions (to Firefox, Thunderbird, other applications)
- BugMeNot, AdBlock, MiniT, Sage, Enigmail, etc.
¥Applications (like Firefox, Thunderbird, etc)
Today, there are two obvious uses for XULÉ

Firstly, using XUL to build extensions to existing applications, like Firefox or Thunderbird (and there are a large number of these right now, hundreds in fact)É

Secondly, to build entire applications like Firefox itself. IÕm going to talk a little bit later on about how the XULRunner project will make it easy to create full featured cross platform applications with low deployment overhead on systems that already have Firefox installed.
