Google is Killing Ad Blockers in Chrome

Main summary

Key takeaways

News and Commentary

Overview

Google is moving to disable the Manifest V2 (MV2) APIs in Chrome and related Chromium-based browsers, which is expected to break many existing ad blockers—most notably uBlock Origin. Chrome will warn users via popups to remove or replace affected extensions.

Commentary: Key Claims and Impacts

Why MV2 is being deprecated (claim)

  • The deprecation is widely suspected to be intended to reduce the effectiveness of ad blockers, allowing Google to earn more from its ad network.

What happens to uBlock Origin users in Chrome

  • Users are pushed toward uBlock Origin Light (MV3) as a fallback.
  • However, this comes with reduced blocking capability.

MV3 limitations vs MV2

The video argues that MV3 is significantly more constrained than MV2, lacking features such as:

  • Dynamic filtering
  • Per-site disabling of remote items like fonts and JavaScript

Result: users may have less control over intrusive advertising.

Workarounds for MV2 Users (Especially Enterprises)

A less disruptive path mentioned is:

  • Modifying policy settings (e.g., Windows registry / Mac/Linux policy preferences) to extend MV2 support.

The video also claims:

  • Chrome for Enterprise may ship with MV2 policy enabled by default due to legacy internal software that depends on older extension capabilities.

It adds that:

  • Other Chromium browsers (e.g., Brave and Edge) rely on similar MV2-availability flags.
  • Still, MV2 is expected to be fully dead across Chromium platforms after June 2025.

Long-Term Alternatives

Brave

  • Includes a built-in ad blocker (rewritten in 2019).
  • Uses faster rule-matching methods and is claimed to be ~69× faster on average.
  • Reportedly offers fewer configuration options than uBlock Origin.

Firefox (recommended)

  • The video recommends switching to Firefox to keep using uBlock Origin.
  • Rationale: Firefox uses a different browser engine, described as immune to Google’s MV2 changes.
  • The video further claims that Mozilla and uBlock Origin developers have indicated MV2 won’t be deprecated on Firefox.

Safari / WebKit

  • Suggested as another engine-independent option, but with caveats:
    • uBlock Origin isn’t available in Safari
    • Filtering quality may be weaker

Network-Wide DNS Filtering (e.g., “Pi-hole”)

  • Can block ad/tracking domains across an entire network, including:
    • Phones
    • Ad-supported apps

Downside (as described in the video):

  • It’s coarse (“axe vs scalpel”)
  • It can’t reliably target ads when the ads share the same domains as desired content (e.g., YouTube or Google search ads), where more precise local filtering is needed.

Overall Conclusion

For the strongest ad-blocking results going forward, the video frames Firefox + uBlock Origin as the best path, and emphasizes that continued support for these projects will be important as the ecosystem moves further away from Chromium’s MV2-era capabilities.
