Ad Blockers Will Continue Functioning in Chrome Despite Manifest V2 Support Ending

• June 14, 2026

Concerns recently arose regarding the potential disruption to ad blockers in Google Chrome following the planned end of support for the Manifest V2 extension standard. Reports suggested that popular ad blockers like uBlock Origin might cease functioning after Chrome version 150, scheduled for release later this month. However, these claims have been formally disputed.

Ad blockers remain supported despite Chrome’s extension update

Google announced plans to phase out Manifest V2, an older framework used for browser extensions, with Manifest V3 being the modern replacement. The transition aims to enhance browser security and privacy features but has raised apprehensions within the ad-blocking community regarding compatibility and continued effectiveness.

Andrey Meshkov, co-founder of the privacy-focused software company AdGuard, has clarified that ad blockers will continue to work in Google Chrome even after the discontinuation of Manifest V2 support. This reassurance directly contradicts earlier media reports that predicted disruptions or complete blockage of extension functionality for ad blockers like uBlock Origin.

Manifest V2 has been foundational in enabling complex ad-blocking filters and content blocking capabilities. Manifest V3 introduces significant technical changes, including alterations to background processes and API features, which initially caused uncertainties about extension performance and flexibility.

Nevertheless, with contributions and feedback from the developer community, browser vendors including Google have implemented solutions ensuring that essential features leveraged by ad blockers remain viable. This collaborative effort allows extension developers to adapt their tools without losing core blocking effectiveness while aligning with the updated security protocols of Manifest V3.

The explicit confirmation from AdGuard’s leadership serves to ease the concerns of millions of users relying on ad blockers for enhanced privacy and safer browsing. It also underscores ongoing efforts by Google and extension developers to balance innovation with user experience preservation.

As browser ecosystems continue evolving, stakeholders from multiple sides emphasize transparent communication to prevent misinformation about technology transitions. The proactive stance taken here exemplifies that changes to extension frameworks do not necessarily compel end-of-function scenarios for widely used tools.

In summary, despite a significant technical shift in how Chrome handles extensions starting with version 150, current evidence supports the continued operability of major ad blockers. Users can expect their ad blocking extensions to remain functional, subject to updates aligning with the Manifest V3 environment.

Ad blockers such as uBlock Origin will remain operational in Google Chrome after the discontinuation of Manifest V2 extension support.
