Even in 2025, major browsers like Chrome, Safari, and Firefox block pop-ups by default, but you can enable pop-ups for specific websites. In Chrome, go to Settings > Privacy & Security > Site Settings > Pop-ups and redirects, and add specific sites to "Allow". On Safari (Mac/iPhone), you can also disable the “Block Pop-ups” option by going to settings. In Firefox, you also have to allow the site in the “Permissions” section. You have to see to it that you only enable pop-ups for trusted sites so that there is no security risk.
