There is ublock origin lite[0] on chromium which is the v3 compliant ad blocking strategy, but it is severely limited by the new ruleset and limitations, being a crippled version.

There are more details available on this fan site of ublock[1]:

> What Was Manifest V3?

> Manifest V3 was Google's major update to the Chrome extension platform. The most significant change was replacing the webRequest API with the more limited declarativeNetRequest API. While Google cited security and performance benefits, this change removed capabilities that content blockers like uBlock Origin relied on for effective ad and tracker blocking.

> How This Affected uBlock Origin

> uBlock Origin used the webRequest API to intercept and block network requests in real-time. The replacement declarativeNetRequest API has hard limits on the number of filter rules (previously 30,000, now 330,000) and lacks the dynamic filtering capabilities that made uBlock Origin so effective. As a result, the full uBlock Origin extension was removed from the Chrome Web Store in late 2024. Chrome permanently disabled all remaining MV2 extensions in July 2025.

Most ad blockers do already use MV3, uBlock Origin is the only one still using V2 as far as I know.

There are some drawbacks to V3, however none prevent creating an effective ad blocker, as demonstrated by the fact that many exist. Though saying that doesn't make for nearly as effective clickbait...
