About pop-up ads and windows in Safari

Learn how to block pop-up windows and handle persistent ads on your iPhone, iPad, iPod touch, or Mac.

Pop-ups can be ads, notices, offers, or alerts that open in your current browser window, in a new window, or in another tab. Some pop-ups are third-party ads that use phishing tactics—like warnings or prizes—to trick you into believing they’re from Apple or another trusted company, so you’ll share personal or financial information. Or they might claim to offer free downloads, software updates, or plugins, to try to trick you into installing unwanted software.

Unless you’re confident of an ad’s legitimacy, you should avoid interacting with pop-ups or webpages that seem to take over your screen. Here are additional tips that can help you manage pop-ups and other unwanted interruptions.

Check and update your software

Always make sure you install the latest software updates for all your Apple products. Many software releases have important security updates and may include improvements that help control pop-ups.

The safest place to download apps for your Mac is the App Store. If you need third-party software for your Mac, and it isn’t available in the App Store, get it directly from the developer or another reliable source, rather than through an ad or link.

Check Safari settings and security preferences

Make sure Safari security settings are turned on, particularly Block Pop-ups—for pop-up windows—and the Fraudulent Website Warning.

On your iPhone, iPad, or iPod touch, go to Settings > Safari and turn on Block Pop-ups and Fraudulent Website Warning.

On your Mac, you can find these options in Safari > Preferences. The Websites tab includes options to block some or all pop-up windows, and you can turn on fraudulent site warnings in the Security tab.

Pop-ups and ads in Safari

If you see an annoying pop-up ad in Safari, you can go to the Search field and enter a new URL or search term to browse to a new site. If you don’t see the Search field on your iPhone, iPad, or iPod touch, tap the top of the screen to make it appear.

Some pop-ups and ads have fake buttons that resemble the close button, so use caution if you try to close a pop-up or ad. If you’re unsure, avoid interacting with the pop-up or ad and close the Safari window or tab.

On your Mac, you can also update your settings to prevent windows from opening again after you close Safari, or just press and hold the Shift key when you open Safari.

If you might have installed adware or other unwanted software on your Mac

If you see pop-ups on your Mac that just won’t go away, you might have inadvertently downloaded and installed adware (advertising-supported software) or other unwanted software. Certain third-party download sites might include programs that you don’t want with the software that you install.

If you think that you might have malware or adware on your Mac, update to the latest version of macOS. If your Mac is already running the latest version, restart it. macOS includes a built-in tool that removes known malware when you restart your Mac.

Check your Applications folder to see if you have any apps that you didn’t expect and uninstall them. You can also check the Extensions tab in Safari preferences to check if you installed any unnecessary extensions that you’d prefer to turn off. If you continue to see advertising or other unwanted programs on your Mac, contact Apple.

Configuring your web browser to allow pop-up windows

Most web browsers include a feature to block pop-up windows. While this may eliminate unwanted or bothersome pop-up windows, the feature sometimes can impede the functionality of legitimate or useful websites.

Some popular Penn-affiliated websites requiring pop-ups include U@Penn and the Penn Online Directory.

Follow the instructions below to configure your web browser to allow pop-up windows for your selected websites.

• Apple Safari (macOS)
• Google Chrome .current (Windows/macOS)
• Mozilla Firefox.current (Windows/macOS)
• Microsoft Internet Explorer (Windows)
• Microsoft Edge (Windows 10 only)

Note: If you have installed third party applications to block pop-ups (examples include the Google, MSN, and Yahoo! toolbars), be sure to consult the vendor documentation to allow pop-up windows for desired websites.

Safari (macOS)

Safari for macOS has no per-website control over blocking pop-up windows. Pop-ups are either blocked, or they are not. To allow pop-ups:

1. From the Safari menu, choose Preferences. and click the Security tab.
2. Ensure the Block pop-up windows option is not checked. Unchecking this option will allow pop-ups.
3. To block pop-ups once again, check the Block pop-up windows checkbox.

Note: If you are concerned about allowing pop-ups globally for all websites that you browse, consider using another web browser that allows website exceptions such as Chrome or Firefox.

Chrome .current (Windows/macOS)

1. Open Chrome, then go to the web page that you want to allow pop-ups.
2. In Chrome’s URL window, highlight the entire web address of the current page, then choose the Copy command from the Edit menu or right-click and choose the Copy command.

Notes: Pasting the web address of a page you wish to allow pop-ups is recommended, rather than typing the generic main web address. For example, you might visit www.example.com/requirepopup.html, but the page is actually hosted at popup.example.com/forms/popupform.html. In this example, you must allow popup.example.com, not www.example.com. Note also that entire websites must be allowed, not individual directories or pages, so in this example Chrome will automatically add the top level popup.example.com to its Allowed sites.
