How do i block ALL popups?

Hi Bobby, In the Menu bar at the top of the screen, click Firefox and select Settings (or Preferences, in some cases). SelectPermissions and data on the left. Go down to the Permissions section. Check the box next to Block pop-ups and third-party redirects to disable the pop-up blocker altogether.
