How to choose an ad blocker extension
The four ad blockers are free to install from the Chrome Web Store, and Adblock Plus and AdBlock also sell an optional Premium. The real differences are who maintains them, what they block by default, and what extra settings or checks they add.
- Open source or commercial. uBlock Origin Lite is open source and made by Raymond Hill, the author of uBlock Origin. AdGuard AdBlocker is open source too. AdBlock and Adblock Plus are both made by eyeo, which also sells optional Premium plans.
- Acceptable Ads. Both Adblock Plus and AdBlock have Acceptable Ads on by default, so some ads still show until you switch it off. uBlock Origin Lite has no such program in anything we read.
- Filter lists. uBlock Origin Lite uses uBlock Origin’s default lists, with three filtering modes. Adblock Plus lets you choose which lists are on. On Manifest V3, AdGuard AdBlocker’s filters only update when a new version ships.
- Extras beyond ads. AdGuard AdBlocker adds phishing-site checks and a rules editor. AdBlock’s optional Premium lists extras such as cookie-banner blocking. Adblock Plus lets you block a single page element from the right-click menu.
- Manifest V3. All four ad blockers run on Chrome’s current Manifest V3 extension platform.
- YouTube sponsor reads. SponsorBlock is not an ad blocker. It skips sponsored segments inside YouTube videos, which ad blockers cannot do, so install it next to one of the four.

Which is the best ad blocker extension for Chrome?
For most people, uBlock Origin Lite is the best ad blocker extension for Chrome. It is a lighter Manifest V3 extension from uBlock Origin’s developer, it is open source, and it uses uBlock Origin’s default lists. The trade-off is that Manifest V3 limits what it can do, and the developer says so plainly.
If you want a commercial blocker with optional Premium, AdBlock or Adblock Plus are the options, but check the Acceptable Ads setting first.
Does uBlock Origin still work in Chrome?
No. The original uBlock Origin was removed from the Chrome Web Store on 31 August 2026, according to its own README. uBlock Origin Lite is a separate, lighter Manifest V3 extension by the same developer, not an automatic replacement. It uses the same default filter lists but applies them through Chrome’s declarative content-blocking API.
Which ad blockers work with Manifest V3?
All four ad blockers work with Manifest V3, Chrome’s current extension platform. uBlock Origin Lite runs its filtering rules through the declarativeNetRequest API. AdGuard AdBlocker has been fully MV3 since version 5.0.91 (September 2024). AdBlock has been MV3 since 6.0.0 (23 April 2024), and Adblock Plus since 4.0 (30 April 2024).
Which ad blocker blocks every ad by default?
Choose uBlock Origin Lite if you want no Acceptable Ads program at all. AdBlock and Adblock Plus both have an Acceptable Ads setting that lets some ads through, and it is on by default in both. Turn it off in the settings if you want more blocked.
Does SponsorBlock block YouTube ads?
No. SponsorBlock is not a classic ad blocker. It skips sponsored segments that creators place inside their own videos, using segments submitted by other users. It does not remove the ads YouTube itself plays, so use it alongside an ad blocker from this list. We could not read its developer’s privacy policy when we checked; read it before installing.
Which ad blocker also protects against malware?
AdGuard AdBlocker is the pick that adds checks for phishing sites. Its privacy notice says the check uses Safe Browsing with hash prefixes. uBlock Origin Lite does not describe a similar check, so compare the two side by side before you choose one, and read each privacy notice before you install.
