Travis, move your pointer up to the top of the browser and select Tools.
Move the pointer down the menu that appears and select Popup Manager.
Select About Popup Blocking.
Below the query, "Would you like to block popups and select preferences now?" select Yes.
In the Preferences window that opens click a check mark into "Block unrequested popup windows."
Click the "OK" at the bottom of the Preferences window.

If this doesn't work, let me know & I'll give you some more guidance (or misguidance).
