Web Request and Declarative Net Request: Explaining the impact on Extensions in Manifest V3

One of these changes is to move away from the blocking version of the Web Request API [which uBlockOrigin uses] towards a new API… this change is meant to give developers a way to create safer and more performant ad blockers…we are currently planning to change the rule limit from maximum of 30k rules per extension to a global maximum of 150k rules.

There’s been a lot of confusion and misconception around both the motivations and implications of this change, including speculation that these changes were designed to prevent or weaken ad blockers. This is absolutely not the goal. In fact, this change is meant to give developers a way to create safer and more performant ad blockers.

interesting - i like what they say, but not sure about this…

… we are currently planning to change the rule limit from maximum of 30k rules per extension to a global maximum of 150k rules.

i don’t get it - is uBO on Chrome currently limited to 30k filter rules? because just one of Fanboy’s lists alone can exceed 50k rules

As part of an effort to increase user security and privacy, Chrome is planning a number of changes to the extensions platform.

Hehe, Chrome and user privacy.
