What is OpenIn?
OpenIn is a macOS app that lets you choose which browser or application handles any link you click. It integrates with browser profiles, so you can redirect links to a specific profile, browser, or app based on your own rules and conditions.

Firefox Add-on Features

• Toolbar icon
  Quickly open the OpenIn App Selection dialog to send any link to another browser, profile, or application.
• Context-menu command
  “Open in OpenIn” appears when you right-click a link, letting you forward it directly without leaving the page.
• Automatic link overrides
  In the add-on settings, configure domains or link patterns so they’re sent to OpenIn automatically.
