External Application Button (WebExtension) by Andy Portmen

External Application Button allows you to define highly customizable toolbar button and context menu items for Firefox browser. Using this application for instance you can send current page to Chrome, Opera, or Internet explorer browsers. Or send selected text to a text editor like Notepad++ or Sublime Text. It is even possible to directly send image URLs to a photo editor of your choice or send download links to an external download manager like FlashGot extension in Firefox.

Note that in order for this application to work, there is a minimal native client that needs to be installed manually. Instruction on how to install the minimal client is shown once an application is added to the list. For more info watch the video tutorials or visit add-on's homepage.
