Google engineers have proposed changes to the open-source Chromium browser that will break content-blocking extensions, including various ad blockers.
Adblock Plus will most likely not be affected, though similar third-party plugins will, for reasons we will explain. The drafted changes will also limit the capabilities available to extension developers, ostensibly for the sake of speed and safety. Chromium forms the central core of Google Chrome, and, soon, Microsoft Edge.
In a note posted Tuesday to the Chromium bug tracker, Raymond Hill, the developer behind uBlock Origin and uMatrix, said the changes contemplated by the Manifest v3 proposal will ruin his ad and content blocking extensions, and take control of content away from users.
Content blockers may be used to hide or black-hole ads, but they have broader applications. They’re predicated on the notion that users, rather than anyone else, should be able to control how their browser presents and interacts with remote resources.
Manifest v3 refers to the specification for browser extension manifest files, which enumerate the resources and capabilities available to browser extensions. Google’s stated rationale for making the proposed changes, cutting off blocking plugins, is to improve security, privacy and performance, and supposedly to enhance user control.
uBlock origin is not only an ad blocker but also an important privacy and security tool
