Has anyone been using the v3 compatible version of uBlock Origin? Have you noticed much of a difference? From what I read there isn't supposed to be much of a difference?

I have been using the Firefox version of it for more than a year by now, basically as soon as it came out. I commented on HN that I was going to do it: https://news.ycombinator.com/item?id=37219071

There's no difference whatsoever.

And it's not surprising because on my iOS device I've been using similarly architected content blockers since 2015. There's no issue with declarative ad blocking.

Of course this differs with the kind of sites you visit. So you need to try it on your own. I can believe that perhaps for some people this is a downgrade, but don't automatically assume uBlock Origin Lite won't work well for you.

Anyone jumping up and down about MV3 while using Mac or iOS are hypocrites, since MV3 is essentially doing the same thing Safari did years ago, finally matching the security and the privacy in that regard. The reduction in adblocking is so miniscule in aggregate - since declarative approach will always cover all the major advertisers - that it's not even a meaningful "trade-off".

It’s similar, but not the same. Safari lets you dynamically generate rules that are then compiled for privacy and efficiency. The limits were increased to 150000 rules per content blocker due to user demands [1]. And each extension can have multiple content blockers.

MV3 has a measly 30000 static rule limit. These rules are included with the extension and cannot be updated dynamically. And a 5000 dynamic rules limit. [2]

EDIT: Chrome now has a 300000 shared pool for static rules for extensions that go over their 30000 limit. And a 30000 dynamic rule limit [3].

The limit is 330000 rules:

"Based on input from the extension community, we also increased the number of rulesets for declarativeNetRequest, allowing extensions to bundle up to 330,000 static rules and dynamically add a further 30,000." https://blog.chromium.org/2024/05/manifest-v2-phase-out-begi....

It looks like it’s a shared quota now with a minimum per extension [1].

Still sucks that the rules are static though. AdGuard devised a method to diff ruleset changes with the built in rules to generate dynamic rules between extension updates. So, I guess it works.
