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.

In the past, origin has just changed to work again. Is that out of the question now?

The problem is the core of how Origin works. Right now, Origin sits in the stream of data that comes in from a website, and uses its own filtering to block or change things that are unwanted. That mechanism was removed in Manifest V3. Now it has to supply to the browser a list of things to block or change, and there's a limit to how many things can be on that list.
There's a new version of uBlock that works with Manifest V3 but it doesn't work as well as the V2 version.

Thank you for the answer but I'm still not certain if there's another way it could do it.
