External Application Button (WebExtension)

External Application Button is a Firefox extension that allows users to create highly customizable toolbar buttons and context menu items. With this extension, you can seamlessly send the current page to other browsers like Chrome, Opera, or Internet Explorer, or send selected text to text editors such as Notepad++ or Sublime Text. It also lets you send image URLs to your preferred photo editor or transfer download links to external download managers like the FlashGot extension.

To use this extension fully, a minimal native client must be installed manually, with installation instructions provided within the add-on interface. This makes integration with external applications smooth and efficient. Video tutorials are available for Windows, Linux, and Mac users, and further support can be found in the add-on's discussion section. This tool streamlines workflow by bridging Firefox with external applications directly from the browser interface.
