To allow pop-ups in Safari, the steps differ slightly depending on whether you are using a Mac or an iPhone/iPad.

On Mac

1. Open Safari.
2. From the top menu bar, choose Safari > Settings (or Preferences).
3. Click the Websites tab.
4. In the left sidebar, scroll down and select Pop-up Windows.
5. You will see a list of currently open websites and configured websites. For a specific website, use the pop-up menu next to it and select Allow to enable pop-ups for that site.
6. To allow pop-ups on all websites, find the setting at the bottom labeled When visiting other websites and choose Allow from the drop-down menu.

If you want to block pop-ups again, you can select Block or Block and Notify instead

On iPhone and iPad

1. Open the Settings app.
2. Scroll down and tap Safari.
3. Find the Block Pop-ups toggle.
4. Turn off the toggle to allow pop-ups.

Note that on iOS, pop-up blocking is a global setting; you cannot allow pop- ups for individual sites only. If you want to allow pop-ups for a specific site, turn off the blocker, visit the site, then optionally turn the blocker back on after

. This will enable pop-ups according to your preference on Safari across your Apple devices.
