The only reason anyone knows about the switch between manifest 2 and 3 is that the only meaningful difference is the crippled ad blocking ability. Nobody knows any other difference unless they are an extension developers or worked on making the Internet a worse place.

Right, but there is no meaningful difference in terms of ad blocking ability.

It's all theoretical. In practice, uBlock Origin Lite works amazingly on MV3. In my experience, it blocks all the ads. And I've been using it for a while now.

I mean you’re right about the awareness of it due to ad blocking but

> Nobody knows any other difference unless they are an extension developers or worked on making the Internet a worse place.

MV3 comes with a ton of security improvements over MV2, a side effect is the perceived weakening of ad blocking extensions but the benefits outweigh the cons.

MV2 effectively allowed a permanently open RCE pathway.

The browser itself should ideally be handling ad blocking as it’s more effective and efficient at it (Brave, Vanadium, Trivalent).

Safari has already been on an MV3-like extension system for years yet only Chromium draws ire. I mean they got flack at first but it died off and now there’s no real difference.
