By default, the Chrome Web browser for Windows blocks most unwanted pop-ups, leaving you the option of viewing blocked pop-ups on a case-by-case basis. To adjust the pop-up blocker settings to allow or deny all pop-ups, or to create exceptions that allow or deny pop-ups from specific websites, open the Content Settings window from the Privacy section of Chrome's settings. If Chrome fails to block pop-ups no matter your settings, however, your computer might be infected by malware.
Open the Chrome menu and click "Settings." Alternatively, open the settings page by entering "chrome://settings" in the address bar.
Type "Privacy" without quotation marks into the "Search Settings" box to filter Chrome's long list of options. Press the "Content Settings" button in the search results.
Scroll down in the Content Settings window to the Pop-ups section. Choose "Do Not Allow Any Site to Show Pop-ups (Recommended)" to block all pop-ups other than the exceptions you have set. Alternatively, pick "Allow All Sites to Show Pop-ups" and press "Manage Exceptions" to block only pop-ups on specific sites.
Type a website's address in the "Hostname Pattern" box and choose "Block" in the Behavior column to block pop-ups on a specific site when using the "Allow All" option. When using the "Do Not Allow Any" option, add websites and choose "Allow" to create exceptions for sites with useful pop-ups.
To view a blocked pop-up, from the address bar click the pop-up icon resembling a computer window with an "X," and choose the pop-up to view.
Chrome installations on public computers, or those at work or at school, might lock the pop-up blocker settings so that only administrators can change the options.
Chrome's pop-up blocker misses some pop-ups, but if you regularly see pop-up ads -- especially when browsing sites that do not usually use intrusive advertising -- you might have malware on your computer. Run an anti-virus program and malware scanner, or use the Chrome Software Removal Tool (link in Resources) to search for the problem. If these scans don't fix the issue, reset your Chrome settings: Search for "Reset" on the Settings window and press "Reset Settings."
