Sharing work apps while using Firefox (Mac)

Tandem app-sharing is enabled for Windows users, but Mac users will need to add a Firefox Extension to add this feature:

Install this Firefox extension: https://addons.mozilla.org/en-US/firefox/addon/add-url-to-window-title/

After you install it,  select "tools" and "Add-ons and themes" from the Firebox menu

Click on the extension, click on "preferences" and check the “Show the full URL” box
