There are two ways to block ads in Chrome. Chrome’s own settings block intrusive ads and pop-ups, with nothing to install. On a computer, an ad blocker extension from the Chrome Web Store blocks most of the other ads. The fastest route on a computer:
- Open uBlock Origin Lite in the Chrome Web Store.
- Select Add to Chrome, then Add extension if Chrome asks.
- Reload the page you were on. The blocker is now working.

Use Chrome’s built-in intrusive ad blocker
Chrome blocks ads on sites with poor ad experiences: too many ads, ads with flashing graphics or autoplaying audio, and ad walls before you can see the content. Steps from Google’s help on intrusive ads:
- In Chrome on your computer, select the three-dot More menu at the top right, then Settings.
- Select Privacy and security, then Site settings.
- Under Content, select Additional content settings, then Intrusive ads.
- Under Default behavior, choose the option that blocks intrusive ads. The other option, “Any site you visit can show any ad to you”, turns the blocker off.
To allow ads on one site you trust, go to that site, select View site information to the left of the web address, then Site settings. Next to Intrusive ads, select Allow, and reload the page.
This blocker only removes ads on sites that break the ad rules. Ordinary ads on other sites still show, which is what an extension is for.
Block pop-ups and redirects
Steps from Google’s help on pop-ups:
- Select the three-dot More menu, then Settings.
- Select Privacy and security, then Site settings, then Pop-ups and redirects.
- Choose the default that does not let sites send pop-ups or use redirects.
When Chrome blocks a pop-up you actually wanted, a “Pop-up blocked” icon appears in the address bar. Select it, then pick the pop-up, or choose Always allow pop-ups and redirects from that site and select Done. More detail is in our pop-up blocker guide.
Install an ad blocker extension
For a computer, these blockers were checked live in the Chrome Web Store on the day this page was written:
- AdGuard AdBlocker, by Adguard Software Limited
- Ghostery AdBlocker for Privacy, by Ghostery GmbH
- Adblock Plus, by eyeo GmbH (shows some non-intrusive “Acceptable Ads” by default; you can turn that off)
- AdBlock, by ADBLOCK, INC. (also leaves non-intrusive ads unblocked by default; you can turn that off)
- uBlock Origin Lite, by Raymond Hill, linked at the top of this page
The original uBlock Origin is no longer in the Chrome Web Store. Google removed the last Manifest V2 extensions from the store on August 31, 2026 (Google’s timeline). The ad blocker comparison explains what changed.
To install one, open its store link and follow Google’s Chrome Web Store steps:
- Select Add to Chrome.
- If Chrome asks, select Add extension to approve its permissions.
- To keep the blocker’s icon in view, select the Extensions icon (the puzzle piece) to the right of the address bar and select Pin next to it.
Allow ads on a site, or turn a blocker off
Each blocker has its own settings, which open when you select its icon next to the address bar. Look there for the option to stop blocking on the site you are on, then reload the page.
To turn a blocker off on every site, or remove it, open the Extensions page:
chrome://extensionsPaste that into the address bar, or open the three-dot menu and select Extensions > Manage extensions. Use the switch next to the blocker to turn it off, or select Remove.
Android, iPhone and iPad
Ad blocker extensions are installed in Chrome on a computer. If you find an extension in Chrome on your phone, Google’s help shows the button as Add to Desktop: the extension is installed the next time you open Chrome on your computer. On a phone, use Chrome’s own settings.
Android
- Intrusive ads: tap More (three dots) > Settings > Site settings, then under Content tap Intrusive ads (Google’s steps).
- Pop-ups: tap More > Settings > Site settings > Pop-ups and redirects, and turn off Pop-ups and redirects (Google’s steps).
iPhone and iPad
- Pop-ups: tap More > Settings > Content Settings > Block Pop-ups, and turn it on (Google’s steps).
- Google’s help on the intrusive ad blocker covers computers and Android only.
Ads that keep coming back
Some “ads” are not ads on the page at all.
- Pop-up messages that keep appearing after you block pop-ups: Google says you may have subscribed to notifications from a site. Go to Settings > Privacy and security > Site settings > Notifications to change the default and block sites (Google’s help on notifications). See also stopping Chrome notifications.
- Pop-ups and new tabs that won’t go away, a homepage or search engine that changes by itself, or redirects to pages full of ads: Google lists these as signs of unwanted software. Follow Google’s steps to remove unwanted ads, pop-ups and malware, which include Settings > Reset settings > Restore settings to their original defaults.
