Block pop-ups in Safari on Mac
You can prevent webpages from displaying pop-up windows. However, blocking pop-ups might also block some content you want to see.
Choose Safari > Preferences, then click Websites.
Click Pop-up Windows.
Block pop-up windows for:
A website in the list: Select the website in the right column, then choose the option you want.
All websites that arenβt currently customized: Click the βWhen visiting other websitesβ pop-up menu in the bottom-right corner of the pane, then choose the option you want.
You can see all websites youβve customized under Configured Websites. If you donβt see Configured Websites, either you havenβt customized a website yet, or youβve cleared the list. To configure a website, see Safari Websites preferences.
All websites: Make sure no websites are listed under Configured Websites (to clear the list quickly, select the websites, then click Remove). Click the βWhen visiting other websitesβ pop-up menu, then choose the option you want.
