For a while now the transition away from Manifest V2 (MV2) to MV3 has been on-going and it looks like it is entering its final phase of deprecation, at least, in the case of Google Chrome. A recent discussion thread in the w3c WebExtensions Community Group GitHub repo has highlighted how the latest and upcoming versions of the most popular browser are expected to be its final releases with support for MV2 extensions.
What this essentially means is that the tricks and bypasses that were used to keep MV2 extensions like uBlock Origin and others alive will not work any more on Chrome, or at least not for very long. For example the Windows Registry mod that could extend MV2 availability will cease to function after Chromium version 151.
Brave is by a company who’s in the business of serving ads.
Much like google was back in the day, they’re trying to obtain market share with a product that they can easily manipulate after the fact and rely on people not jumping ship as things get progressively worse and worse bit by bit
Think of the “approved ads” era followed by the “enhanced security features” which made it so your block list couldn’t be updated at a moments notice and now it’s being stripped entirely.
Better to avoid it entirely and just use Firefox or a derivative thereof
