What is an XBL file?
File created in the XML Binding Language (XBL) format, an XML format used to specify the presentation of .XUL user interface widgets; contains "bindings," which declare the layout of the XML interface elements; enables developers to change the look of widgets without having to modify the core functionality.
NOTE: The XBL specification was developed by the Mozilla Project and was included in many of the organization's software applications.
