Google is planning to replace Manifest V2 with V3 soon after June 2024.

Among other things, this will break content blockers like uBlock Origin.
Resolves YES if, in any stable desktop Chrome release in 2024, Manifest V2 extensions are disabled by default for 100% of users. The rollout must remain at 100% for at least a week.
Per the market description, it resolves yes if there's a stable Chrome release in 2024 wherein Manifest V2 extensions are disabled by default for all users. While there remains, for now, a togglable switch to reenable support for them, it does sound like they're going to be disabled by default going forward.
@Tulip On a clean install of current Chrome Stable (version 131), Ublock Origin (a Manifest V2-exclusive extension) can still be installed from the Chrome Web Store and works out of the box without having to change any settings or toggle a switch to enable it. This is also the case in current Chrome Canary (version 133). Functionality to support fully disabling Manifest V2 extensions at all was only added just last week (but is itself disabled).
Based on Chrome's release schedule (https://chromiumdash.appspot.com/schedule) 131 (the current Stable version) will be the last Stable release during 2024. I consider it highly unlikely that the Manifest V2 extension deprecation status will change during the current Stable version.
