Google Chrome users who still rely on older ad-blocking extensions may soon need to switch to newer alternatives. Google is preparing Chrome updates that will remove the remaining workarounds allowing legacy ad blockers to continue functioning.
The change affects extensions built on Manifest V2, Google’s older Chrome extension platform. Popular tools such as the original uBlock Origin were built around Manifest V2, but Google has been shifting Chrome extensions to Manifest V3, a newer framework that changes how browser extensions operate.
What Is Changing in Chrome?
Chrome versions 150 and 151 are expected to remove the last remaining code references tied to Manifest V2 support. Once this change is fully in place, older ad blockers that depend on Manifest V2 will no longer work in supported versions of Chrome.
This means users who have been relying on loopholes or temporary workarounds to keep older ad blockers active may lose that option. Going forward, Chrome will only support ad-blocking extensions that are compatible with Manifest V3.
Why Google Is Removing Manifest V2 Support
Google has been phasing out Manifest V2 for some time. The company says the move is connected to security, performance, and long-term maintenance concerns.
Manifest V2 extensions require support for older browser functionality that Google no longer wants to maintain. By removing the remaining Manifest V2 code, Google is simplifying Chrome’s extension system and pushing developers toward the newer Manifest V3 standard.
What This Means for uBlock Origin Users
The original uBlock Origin extension was built for Manifest V2, which means it will no longer work in Chrome once the older platform is fully removed.
Users who want to continue blocking ads in Chrome may need to switch to Manifest V3-compatible tools, such as uBlock Origin Lite or other updated ad-blocking extensions available through the Chrome Web Store.
However, some users may notice differences between older and newer ad blockers. Manifest V3 changes how extensions can filter and block web requests, which has led to ongoing debate among users, developers, and privacy advocates.
Can Users Switch Browsers?
Yes. While Google Chrome is removing Manifest V2 support, other browsers may choose to continue supporting older extension systems for a longer period.
Users who prefer the original uBlock Origin experience may consider browsers that still support Manifest V2-based extensions. Browser support can change over time, so users should check the latest extension compatibility before switching.
Why This Update Matters
Ad blockers are widely used by people who want faster browsing, fewer distractions, and more control over online tracking. Google’s latest Chrome update is important because it marks another major step in the browser’s move away from older extension technology.
For everyday users, the key takeaway is simple: older ad blockers are being phased out in Chrome, and newer Manifest V3-compatible extensions will become the main option.
Final Thoughts
Google Chrome’s upcoming changes will close the remaining loopholes that allowed older ad blockers to keep working. While this may improve Chrome’s extension security and reduce technical debt, it also limits support for legacy tools that many users still prefer.
Chrome users who depend on ad blockers should check whether their current extension is Manifest V3-compatible and prepare to switch if necessary.
