Open the trusted site in Safari. Go to Safari → Settings → Websites → Pop-up Windows and set that site to Allow. Leave the setting for other websites on Block or Block and Notify.
01Open a pop-up just once
Section linkChoose Block and Notify for the site if you want to decide each time. On the site, repeat the action that opens the window, such as opening a statement. When Safari shows the blocked pop-up icon in the address bar, click it to show the window.
02Find the website in Settings
Section linkKeep the website open when you open the Websites tab. Scroll down in the list on the left if you cannot see Pop-up Windows. Older Safari versions may call Settings Preferences. Return to the original page and repeat the action that should open the pop-up.
03Remove the exception when you are done
Section linkFor a site you rarely use, return to Pop-up Windows and set it back to Block and Notify. If a page shows an unexpected prize, urgent security warning or request to install software, close the tab or window without interacting with the message.
