LinuxWhat is the XUL file format?
A file with the .XUL extension is a file known as Firefox XML User Interface Language. It belongs to the Web Files category. This format is associated with Mozilla.
The reliable way to open a .XUL file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
This page lists 6 programs that open .XUL files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
