The key difference between manifest V2.0 and V3.0 with regards to uBO is in V2, the extension has direct access to the browser’s process in making web requests and can make direct changes to those requests. V3 instead requires the extension to declare a list of urls and the browser will act on the extension’s behalf. This is a very simplified explanation that isn’t in any meaningful depth and misses a ton of nuance.

The outcome though is V3 makes it significantly more difficult for uBO to achieve its goals for its users. It is a downright and explicit downgrade, and when Chrome fully moves to Manifest V3.0, uBO’s ability to serve its core functions will likely be diminished.

What a thinly veiled way to insinuate that she won’t participate in good faith, given that good faith participation intrinsically means recusal.
