"Begin disabling installed extensions still using Manifest V2 in Chrome stable"

Notably, Firefox is not removing v2 support (at least for now as of March 2024)

> Firefox, however, has no plans to deprecate MV2 and will continue to support MV2 extensions for the foreseeable future. And even if we re-evaluate this decision at some point down the road, we anticipate providing a notice of at least 12 months for developers to adjust accordingly and not feel rushed.[1]

To my knowledge the “big” chrome engine alternatives aren’t either. I know that Vivaldi and Brave plan on keeping around v2 as long as it is economically feasible

Brave is an odd one. They've publicly stated[1] they plan to support parts of Manifest v2 for a handful of popular addons (uBlock Origin included) by making limited patches, but they make no promises.

It seems Shields was their main focus for MV3 mitigation, much like Vivaldi's now native content blocker made for the same reason (though Vivaldi has said[2] they won't be supporting MV2 past the last Chromium build that includes it).

Why use uBlock on Brave when Brave already blocks ads natively?
