It was clear even when it was first announced in a paper in 2018 that Google’s Manifest V3, a new extension API for Chrome, would present a big problem for developers of extensions designed to block ads, but also trackers and certain types of malware – and for users who want improved privacy and control over their browsing experience.
Manifest V3 was first incorporated into Chrome 88 and released in January 2021. Since early 2022, new extensions using Manifest V2 are no longer accepted in the Chrome Web Store, and the last part of the phasing out of this API, which will break all extensions based on it, is expected to take place by January 2023.
If you use Chrome and want to continue using ad blockers, you should consider switching to another browser. I currently use Brave and although it’s based on Chromium, they already have plans to continue supporting Manifest V2 after Google sunsets it in Chrome.
