        • NOTE: You can remove all allowed site by clicking the Remove All button.

We recommend turning the popup blocker off the first time you visit a website. Some websites use popups as part of the infrastructure, and it is necessary to not block them. After you visit a site for the first time, you can determine if you want to block popups or not.
