About XPI
An XPI, pronounced "zippy", is a Firefox or Thunderbird add-on: a ZIP archive holding a manifest, scripts, styles and images. Unpacking one is a quick way to see what an extension does.
XPI is a Firefox add-on package that other programs do not install. XPI is what Firefox installs add-ons from.
