Short answer: for most people, install uBlock Origin Lite from the Chrome Web Store. It is from Raymond Hill, and its store listing says its default filters match those of uBlock Origin, which is no longer in the Chrome Web Store. Every blocker below was checked live in the Chrome Web Store on the day this page was written, and each link goes to its official store listing.
Ad blocker extensions are installed in Chrome on a computer. On a phone or tablet, use Chrome’s own settings instead; see Android, iPhone and iPad below.
Ad blockers you can install today
| Extension | Made by | Worth knowing |
|---|---|---|
| uBlock Origin Lite | Raymond Hill | Blocks ads and trackers as soon as it is installed. Its listing says it is “entirely declarative”: Chrome itself does the filtering, and the extension only runs when you open its panel or options. |
| AdGuard AdBlocker | Adguard Software Limited | Blocks ads and pop-ups, with extra filters you can switch on in its settings, such as the AdGuard Tracking Protection filter and the Social media filter. |
| Ghostery AdBlocker for Privacy | Ghostery GmbH | Blocks ads and trackers, shows which trackers a site uses, and removes cookie consent pop-ups for you. |
| Adblock Plus | eyeo GmbH | Shows some non-intrusive ads by default under the Acceptable Ads Standard. Its listing says you can turn that off at any time. Some extras need its Premium upgrade. |
| AdBlock | ADBLOCK, INC. | A different extension from Adblock Plus. It also leaves non-intrusive ads unblocked by default, which you can switch off in its settings. Some extras need its Premium upgrade. |
You only need one. If you install a second, turn the first off so you can tell which one is acting on a site.
Which one should you choose?
- You just want ads gone: uBlock Origin Lite. It works straight after installing, with nothing to set up.
- You also want to stop cookie banners: Ghostery removes cookie consent pop-ups as part of its standard features.
- You want to choose extra filter lists: AdGuard lets you switch on extra filters, for example for trackers and social media.
- You already use Adblock Plus or AdBlock: they still work. If you want every ad blocked, turn off Acceptable Ads in the extension’s settings.
How to install an ad blocker
These steps follow Google’s Chrome Web Store help:
- Open one of the store links above in Chrome on your computer.
- Select Add to Chrome.
- If Chrome asks, select Add extension to approve its permissions.
- The blocker starts working. To keep its icon next to the address bar, select the Extensions icon (the puzzle piece) and then Pin next to the blocker.
Install ad blockers only from their Chrome Web Store listings, like the links on this page.
What happened to uBlock Origin?
Chrome extensions are built on a set of rules called a manifest. Google replaced the older Manifest V2 with Manifest V3. Under the old rules, a blocker had to pass all of your web traffic through itself to filter it, which Google says came at a performance and privacy cost. Under Manifest V3, the extension gives Chrome a list of rules and Chrome does the blocking, without the extension seeing the content of your requests. According to Google’s Manifest V2 timeline:
- In October 2024, Chrome began turning off installed Manifest V2 extensions.
- By July 2025, Manifest V2 extensions were turned off for all Chrome users, with no way to turn them back on.
- On August 31, 2026, Google removed all remaining Manifest V2 extensions from the Chrome Web Store.
The original uBlock Origin no longer has a Chrome Web Store listing. uBlock Origin Lite is built for Manifest V3, and its listing says its default filters match uBlock Origin’s. If you still see an old ad blocker in your Extensions list that says it is turned off or no longer supported, remove it and install one of the blockers above.
Allow ads on a site you want to support
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. To turn a blocker off everywhere, open the Extensions page:
chrome://extensionsPaste that into the address bar, or open the Chrome menu (three dots) and select Extensions > Manage extensions. Use the switch next to the blocker to turn it off, or select Remove to uninstall it.
If a site shows ERR_BLOCKED_BY_CLIENT or part of it stops working while a blocker is on, turn the blocker off and reload the page to see if the blocker was the cause. See fixing ERR_BLOCKED_BY_CLIENT for more.
Chrome already blocks the worst ads
Without any extension, Chrome blocks ads on sites with poor ad experiences, such as too many ads, flashing or autoplaying ads, and ad walls before the content (Google’s help on intrusive ads). Chrome also has its own pop-up blocker. Our guide on how to block ads in Chrome shows where these settings are and how to use them.
Android, iPhone and iPad
Chrome extensions, including ad blockers, 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 instead:
- Android: Chrome’s intrusive ad blocking is under Settings > Site settings > Intrusive ads, and pop-up blocking is under Settings > Site settings > Pop-ups and redirects.
- iPhone and iPad: pop-up blocking is under Settings > Content Settings > Block Pop-ups (Google’s help).
Ads that keep coming back
If pop-ups and new tabs keep opening, your homepage or search engine changes by itself, or you are sent to pages full of ads, an ad blocker will not fix it. Google lists these as signs of unwanted software. Follow Google’s steps to remove unwanted ads, pop-ups and malware, or our guide to removing browser hijackers.
