To edit XUL file, we strongly recommend installing software that works with XUL files. Using tools such as XUL Online Editors gives less editing possibilities than software adapted to work with the XUL file format.
The installation of the program that supports the XUL file does not guarantee that the file can be edited. Additional information about the XUL file extension can be found here.
This is the best way. Use any of the programs that support the XUL file to check if it allows you to edit the file. It's safest to download the software from the developer's website. You will find links to the software developers' websites on the subpage of each program. Examples of programs cooperating with XUL files, which make it possible to edit it.
