About XUL files

The .XUL file format is a legacy markup document created by Mozilla to define user interfaces for applications like Firefox and Thunderbird. While revolutionary at its inception for allowing cross-platform UI definitions using XML, it has become a significant source of friction for modern developers. Support for XUL was largely removed from the mainstream Firefox browser in the "Quantum" update, rendering many older extensions and applications obsolete. Because it relies on the specific Gecko rendering engine, .XUL files cannot be opened or rendered natively in standard web browsers like Google Chrome or Microsoft Edge. This proprietary lock-in means you are often left with a file that looks like code but fails to execute. To salvage the data or logic within these files, the best pragmatic approach is converting them to standard formats. For developers migrating legacy add-ons, converting .XUL to HTML and CSS is the necessary (albeit manual) path. For simple inspection or documentation, converting to XML, TXT, or PDF allows you to view the tag structure and attributes without needing a legacy environment like XULRunner.

Convert.Guru analyzes your XUL file, detects the exact format, and lets you read the text inside.

Users also converted JSM, MAFF and MOZLZ4 files.



The XUL Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our XUL converter.
