About XPI files

An .XPI file is a Cross-Platform Installer package used extensively by Mozilla software, including the Firefox web browser, Thunderbird email client, and SeaMonkey. These files function as containers for browser extensions, themes, and plugins, enabling users to add custom features to their software. Internally, an .XPI is simply a compressed ZIP archive that holds CSS, JavaScript, HTML, images, and a manifest file (usually manifest.json or install.rdf).

While highly effective for distribution, .XPI files present challenges for users who wish to inspect the code or verify the contents before installation. Because the operating system treats them as generic files rather than archives, you cannot double-click to browse their contents without specific software. Furthermore, strict code-signing requirements in modern browsers often prevent manual installation of older or modified .XPI files. To analyze the source code, extract assets, or audit the extension for security, the most practical solution is to convert the file to ZIP format. This allows you to unzip the package using standard tools, view the internal structure, and modify resources if necessary.

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