Your test is irrelevant. There is always going to be some tiny percentage of ads that passed through with any ad blocker. So the fact that you have seen ads passed through with it doesn't actually mean anything. The only thing that means anything is how well it operates with your average browsing on a daily basis. And it's such a popular extension because it does an amazing job at blocking ads. That's just a fact. Th…

Your opinion is nothingness. I've tested on the same page that uBo on Firefox blocks more than Chrome, and especially it blocks hidden tracking. That's the reality. All else is irrelevant.

What would prevent sites from just injecting ads into their content server-side? You'll always need both element and request blocking.

That's why GP wrote MITM, not just network blocking. MITM implies the middlebox is trusted by the browser in which it has installed a certificate, so can see and modify content.

Hm, you mean basically to edit all HTML, CSS etc. just in time? This seems significantly harder (concepts spread over files being loaded in parallel or being partially cached etc) than to do it in the browser once everything is loaded.

> What exactly is your gripe with MV3? Running an adblocker is the defining feature of the extensions API. ublock origin has 5x as many users as the second-most-popular extension [1] Supporting ublock isn't just a nice-to-have add-on feature for an extension API, it's literally the only thing most users care about. [1] https://addons.mozilla.org/en-GB/firefox/search/?promoted=re...

But MV3 supports uBlock Origin Lite. Which, in my experience, blocks ads just as well, but also lets pages load significantly faster. MV3 supports uBlock.

UBO lite has a long list of all the types of filters that aren't possibly under MV3: https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-as...

Not sure about page load, but CPU time is about the same between the two: https://x.com/gorhill/status/1792648742752981086/photo/1

This reminds me of how powerful client-side processing has become recently.

How has client-side processing (powerful or not) caused Firefox to reuse Brave's Adblock engine?

Most definitely not as well.

It most definitely is as well. In fact it's better because you don't have the slower page loading times anymore. And everyone I know who used UBO and switched to UBOL has had no complaints about ads not being blocked. Whereas people who don't actually use it love to continue to insist that it's this degraded experience that doesn't work as well. And usually when one of them comes up with an example of some ad not bei…

> It most definitely is as well.

No. uBlock Origin works best in Firefox: https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-b...

uBlock Origin Lite can't do everything uBlock Origin does: https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-as...

If Lite is working for you then good. If you want fuller capability then you want uBlock Origin in Firefox.

I think I failed to explain my point: Just like OSS contributors don't have to agree on anything but the goal of the project and how to treat each other while working on it, people shouldn't decide what software to use based on anything but the technical merits of the program. Also, you don't have to benefit Brendan Eich by using Brave. Turn off the crypto and AFAICT Brave gets no money from you. Not that I actually…

But why? You haven't given an argument. In our capitalist societies, I have two avenues of influencing public life: my vote and my wallet. Rich people like Brendan Eich have a much more impactful vote due to their capital, so the only real avenue I have left is my wallet. So please explain: why shouldn't I use my wallet to prevent people like Brendan Eich from shaping society against my friends and loved ones? Why sh…

> But why? You haven't given an argument.

Fair enough. My argument is this: as a society we need to live alongside people we disagree with, perhaps even disagree with fundamentally. My ideal is to not judge people's work in one field by their work (or opinions) in another. I think that this way we can get more done in the fields in which we are in agreement. How well do you think the United States would have gone without the Three-fifths Compromise? IMO not well. Do I agree with the slaveholders? No. Do I think the compromise was better than refusing to work with them at all? Yes.

> Why should I add to his capital while he's actively trying to make the lives of the people I care about worse?

Uh, I don't see this as a matter of capital once you turn off BAT crypto stuff. Please enlighten me.

Why not Cromite (or Ultimatum, Helium)? Hard to understand why someone reading HN use browser without extensions support.

Brave has extensions support. You can get them from the regular chrome store for them.

not on phone

even less reason to use it on desktop
