Email links to a group of tabs in Firefox
One of the great power of the Firefox browser comes from its numerous extensions; extensions are mini-programs that are developed to work as part of Firefox, to enhance its original functionality. In this tutorial, we will show you how to use the Send Tab URLs extension; ("URL" means "Internet address").
Firefox lets you open multiple Firefox windows; each window can have multiple tabs open. Invoking the Send Tab URLs command will create an email, in your default email application, containing a listing of links to all browser tabs opened in the current window. Not only that: it will also use the title of each web page to preface each link.
