The Acceptable Ads Difference

AdBlock is owned by Eyeo GmbH, the same company that created the Acceptable Ads program and operates Adblock Plus. By default, AdBlock allows ads that meet Acceptable Ads criteria (ads where advertisers pay Eyeo for whitelisting). You can disable Acceptable Ads in AdBlock's settings.

ProBlocker does not participate in the Acceptable Ads program and never has. Every ad matching filter rules is blocked.

Open Source vs Closed Source

ProBlocker's code is public on GitHub. You can verify that it collects no data and includes no ad whitelisting by reading the source. AdBlock is not open source; its data practices cannot be independently verified.

Which Should You Use?

Choose ProBlocker if you want

  • No Acceptable Ads, ever — every matching ad is blocked
  • Open-source code you can verify on GitHub
  • No data collection, confirmed by the public source

Sticking with AdBlock?

  • Disable Acceptable Ads in settings — it improves blocking significantly
  • Be aware the code is closed source and cannot be audited
  • Its data practices cannot be independently verified

Install ProBlocker

Get ProBlocker from the Chrome Web Store. It installs in seconds, requires no account, and starts blocking ads immediately.

ProBlocker vs AdBlock: FAQ

Both block YouTube ads. ProBlocker blocks every ad matching its filter rules with no exceptions, while AdBlock enables Acceptable Ads by default — which can let some paid ads through until you disable it in settings.
