How to Block Pop-Ups on Chrome and Keep Them from Returning

Stop Pop-Ups on Chrome with Built-In Settings

Chrome includes a pop-up blocker that stops most unwanted windows before they appear. To confirm it is on, open the three-dot menu in the top-right corner, choose Settings, then Privacy and Security, then Site Settings. Scroll to Pop-ups and redirects and make sure the toggle is set to Blocked. If a specific site keeps slipping pop-ups through, you can add it to the block list manually under the Allowed to send notifications section by clicking the trash icon next to the domain.

This built-in blocker covers most standard browser pop-ups, but it does not stop every kind of interruption. Extensions, malicious scripts, or sites that disguise pop-ups as notification prompts can still get through. The sections below cover how to handle those cases and how to keep the settings working over time.

When Pop-Ups Still Appear: Check for Overrides and Malware

If pop-ups keep showing up even with Chrome's blocker turned on, the most common cause is a per-site override. When Chrome allows pop-ups on a trusted site, that permission can sometimes be reused by an unwanted domain. Go back to the Pop-ups and redirects settings and review the list under Allowed. Remove anything you do not recognize or trust. After clearing the list, restart Chrome and test again.

Another frequent cause is a malicious extension or adware installed on the computer. Extensions can inject pop-ups, change your homepage, or redirect searches. Open the three-dot menu, go to Extensions, and review the list. Remove any extensions you did not install or no longer use. If the problem persists after removing extensions, run a full scan with Windows Defender or a reputable anti-malware tool to check for adware that can reinstall itself.

Block Notification Prompts That Look Like Pop-Ups

Many modern pop-ups are not traditional browser windows but notification prompts asking, "Allow notifications?" If you click Allow, Chrome will show repeated banner-style alerts from that site. To prevent this, go to Settings, then Privacy and Security, then Site Settings, and select Notifications. Set the toggle to Don't allow sites to send notifications. If you still want notifications from a few trusted sites, leave the default setting and manage exceptions by removing any site that should not have access.

Use Chrome's Site Settings to Lock Down Annoying Windows

Beyond pop-ups and notifications, Chrome lets you control additional site behaviors that can feel intrusive. In Site Settings, you can block automatic redirects, stop sites from using background activity, and prevent autoplay media. These controls do not eliminate pop-ups directly, but they reduce the number of unwanted interruptions that come from the same scripts and permissions that enable them.

Keep Pop-Ups from Coming Back

Once pop-ups are under control, a few habits help them stay that way. Keep Chrome updated, since updates often include patches for new adware techniques. Avoid installing browser extensions from unfamiliar developers, and be cautious when clicking "Allow" on permission prompts. Periodically review your site permissions in the Privacy and Security settings so that no site has accumulated pop-up or notification access over time.

When to Use a Dedicated Pop-Up Blocker

Chrome's built-in blocker handles the majority of cases, but some users prefer an additional layer of protection. A dedicated pop-up blocker extension can catch windows that Chrome's default settings miss and can provide a simple on-off switch for individual sites. If you choose to add one, install it from the Chrome Web Store, check its reviews and permissions, and avoid installing more than one blocker at a time, since conflicting extensions can cause pages to load incorrectly.
