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.


I’m having trouble making any sense of your word salad. Are you triggered because someone dared criticize a bonehead move by Mozilla, or are you upset that anyone’s using Firefox’s “abusive ecosystem” in the first place? Neither? Both?
Firefox has lost nearly all of their users and now has less than 4% of the market. Adding a “feature” that makes computers virtually unusable without any indication as to why is yet another reason that’s happened. Nevertheless, if poor implementation of a feature makes for an “abusive ecosystem” it means that by your definition all software is part of an abusive ecosystem.
