What Manifest V3 Means for Brave Shields and the Use of Extensions in the Brave

"For as long as we’re able (and assuming the cooperation of the extension authors), Brave will continue to support some privacy-relevant MV2 extensions—specifically AdGuard, NoScript, uBlock Origin, and uMatrix"

"As of now, the MV2 extensions we plan to explicitly support are AdGuard AdBlocker, NoScript, uBlock Origin, and uMatrix. This feature will be best-effort: we might have to modify support based on either Google’s plans or what extension authors ultimately decide to do. If extensions become stale or obsolete, we may remove support for them rather than offer our users an out-of-date (potentially even unsafe) experience."
