Google is removing Chrome's last remaining workarounds for Manifest V2
extensions, effectively ending support for legacy ad blockers such as
the original uBlock Origin. 9to5Google reports: CyberNews points out a
Chromium commit that removes support for the
"kExtensionManifestV2Disabled" flag, which is referred to as "dead code"
seeing as Chrome no longer supports Manifest V2 extensions. This removal
acts as the final stop for many Manifest V2-based ad blocker extensions
that were still in use today -- the flag was effectively a loophole to
continue using these extensions. A Googler on the commit explains: "MV2
extensions are no longer allowed in any supported version of Chrome, and
we are removing support for them and the associated functionality. We
won't be able to provide / maintain this functionality indefinitely due
to the complexity and tech debt, as well as the security risks it
entails (we've actually found a number of bugs that are specific to MV2
lately). Of course, other browsers can continue supporting these if they
so desire." This will also impact other Chromium-based browsers, though
the comment notes that "other browsers can continue supporting these if
they so desire." Neowin points out that Microsoft Edge and Opera are
likely to follow suit. Chrome 150, set to be released later this month,
will remove this flag, while other leftover bits of Manifest V2 will be
removed in the v151 release.
