PSA re: the wild misreporting about Extensions Manifest v3: declarativeNetRequest *is a list-based blocker*, and that's what's being added. This is the same approach Apple/Safari uses for the same reasons (perf & privacy): https://developer.chrome.com/extensions/declarativeNetRequest …

One of those details is that the size of the list provided by each extension to `declarativeNetRequest` is something that is being studied from the performance point of view. Remember that many extensions can provide lists!

And yes, there is an explicit goal here to remove and reduce use of a much, much slower and more privacy invasive system (blocking `webRequest`). This is a move away from a system that is unsafe in most cases to one that is more like what Apple has shipped.

There *are* open debates about various limits in the new declarative world. But saying "debates rage about the size of a number as tests to verify continue" isn't a great headline...soooo...

For sense of scale for those just joining, Apple limits the total number of rules in the Safari implementation to 50K (if I understand it correctly; doesn't seem documented). Chrome's proposal is 30K *per extension* with evaluation ongoing to raise it: https://developer.chrome.com/extensions/declarativeNetRequest#property-MAX_NUMBER_OF_RULES …

1. With the new system, would uBlock Origin work as well as it does now? 2. What are the concrete security problems that v3 attempts to address? 3. What is the threat model that the designs are being evaluated against?

1.) Depends on where the (evolving) design lands, but I want to say "probably" because I trust the team is listening 2.) Too many extensions can log too much of what you do 3.) Experience

And I should point out Firefox's approach when they slashed legacy extensions was highly problematic for us as well, but they were apparently just following you whom are apparently just following Apple so that explains a lot. Still hampered by lack of certain extensions.

none of us out here have any conception of how big of a problem this is, or where you find this to be an issue. we dont' have any way to appreciate that this can help us. it feels like things are being taken away, & we have nothing but your word to tell us it's for our own good.
