Windows Apps for Firefox Add-ons & Plugins

Firefox Add-ons & Plug-ins, also called Firefox add-ons or Firefox extensions, are mini software programs that let users add functionality to or change the look of the Mozilla Firefox Web browser. Add-ons can enhance existing features or add new ones entirely. Firefox plug-ins work with more specific technology--popular plug-ins enable Flash games, PDF viewing, or Windows video.
