XPI files are ZIP archives renamed that Mozilla applications use to install add-ons. The archives contain JS, CSS, HTML, JSON files combined that comprise the install code. Add-ons with icons have PNG files.
Some Firefox versions allow installing an XPI by drag and drop onto the browser window. To open XPI files, determine the format from the extension and signature. However, different programs use the same extensions incorrectly assigned. Analyzing the file in detail determines the format and program.
Our XPI evaluation shows a special format is very common. Apart from the software file, usually a JAR, XPI archives also contain install.js or install.rdf. These have install instructions. Firefox allows installing XPIs by drag and drop onto the browser.
XPInstall, including Mozilla script, installs the XPI packages. Renaming the XPI extension to ZIP allows opening in WinRAR, WinZip, PeaZip, 7-zip that handle ZIPs.
No conversion method exists for the Firefox XPI extension. The XPI package contains plugins, extensions, themes, dictionaries. It stores scripts and manifests. It is a JAR file and may have multimedia. SDK Add-on library creates Firefox XPIs. Standard Firefox installation handles only digitally signed XPIs.
