External Application Button (WebExtension) - Boost Firefox

External Application Button (WebExtension) is a customizable Firefox add-on. It creates toolbar buttons and context menu items allowing you to share data, including web pages or selected text, with other applications or browsers, such as Chrome, Opera, or Internet Explorer. It can also send image URLs to a photo editor of your choice, or download links to an external download manager. A minimally sized native client is required to be manually installed for functionality.
