Facebook Invite All is a browser extension that makes it easy for you to select all your friends when inviting people to like your Facebook page or to join your Facebook event.
How it works is easy.
After you install the browser extension, you'll see the icon in the top right corner whenever you're on a Facebook invite page.
Just click the icon, and wait. The app will scroll through and check all your friends for you.
