> Disable Firefox's built-in Enhanced Tracking Protection so adblock-rust handles blocking instead.

What concrete and practical differences are there between the two? I'm guessing because this exists, adblock-rust somehow is better than the built-in ETP? In what way?

I'm using ETP + uBlock Origin right now, and can't remember the last time I saw an ad, if I used this instead, what practical differences would I notice?

I've been using ETP plus adblock-rs in Waterfox for 2 weeks. I don't see much a difference compared to ETP + ublock origin apart from some cosmetic filtering. The fact that it's not an extension supposedly allows to block at more layers so it's theoretically better than an extension (https://github.com/BrowserWorks/waterfox/issues/4182)

Note that there are (were?) also some small bugs in the waterfox integration (such as the configuration options sometimes disappearing).

It's memory safe

Can this extension effectively block ads on YouTube? When I manually enabled the Rust ad blocker in about:config and added filter lists there, ads still appeared on YouTube and some porn sites. While uBlock Origin blocks everything.

It should be able to. Waterfox is using roughly the same integration and the maintainer has been seeing reports of YouTube issues, but cannot reproduce it. https://github.com/BrowserWorks/waterfox/issues/4182#issueco...

If it can't, plain old ublock Origin can.

Cool project but I have to ask. Why not use brave?

why use brave, really, when you have firefox? I get it if you're on iOS

Best iOS strategy that comes to mind is Safari:

  -iCloud Private Relay (native VPN-like thing)  
  -uBlock Origin Lite
  -AdGuard DNS

(Using fresh private tabs for small privacy gain?) Better than third-party skinned browsers right? Always happy to be informed otherwise.

(AdGuard does have an option to supplant uBlock in this stack btw, does “advanced” blocking https://adguard.com/kb/adguard-for-ios/web-extension/ which is nice but trust $mm-refusing uBlock dev gorhill forever)

This sounds like good advice so upvoted. I’m a big fan of Raymond Hill¹’s products so I am curious about how much benefit Adguard provides if uBlock Origin is already blocking online trackers, ads and other annoyances.

¹ In this case, the developer – not the musician. I really liked the user interface of uMatrix.

It’s really nice to have ad and tracker domains blocked systemwide though I think you need to be more careful and set your device up as supervised to have more robust blocking (real always-on VPN functionality vs. best effort?).

And even then when I read about defects in Apple software that means a firewall like Little Snitch isn’t perfect (macOS) I think an external device (mobile VPN router?) is going to be essential for some threat models.

(& uMatrix looks great!)

I can see how system-wide blocking would be useful. I’m personally very conservative and wary about apps that I install on my iPhone (I don’t use any ad-supported apps) so the browser is the “attack surface” that I’m most concerned about.

I already use uBlock Origin and iCloud Private Relay (as advised in your original post). I also use Private Browser tabs and regularly remove all “Website Data” from Safari (minor inconvenience in that I have to re-login to sites that I have an account on).

I’ve just installed AdGuard on my iPhone to try it out but see that the DNS protection requires a Premium subscription (it now occurs to me that I could possibly install Wireguard to connect to my VPS where I’m already running my own DNS server). I’ve also `never looked into supervised mode; I always assumed it wasn’t relevant for personal devices.

Thanks for the reply.

I’m a Firefox user myself but there are some very valid arguments against it on Android as well. Firefox on Android is significantly more vulnerable to exploits, lacks internal sandboxing and doesn’t properly isolate tabs from each other.

Firefox and Brave are both profoundly bad on iOS. Scrolling is a nightmare.

everything on iOS is just a safari skin

There is Reynard if you're motivated too (Gecko-based, but it's not ready for prime time yet, and to get good performance you'll have to resort to some workaround to get JIT enabled, as it does not rely on Apple's BrowserEngineKit; one of the goals of the project is giving to not up-to-date iOS devices access to a modern browser).

That's not totally true. Orion supports Chrome/FF WebExtensions, for example. The engine does (practically, even in the EU) have to be WebKit, but that's not the same thing as a "Safari skin."

Brave is malware. https://www.reddit.com/user/lo________________ol/comments/1i...

The top comment response from brave was incredibly rational. Seems like they aren't perfect but are consistent. Am I missing something?

Chrome and Firefox have also both had serious issues. I'm not sure who is the best right now but it's kind of hard to vouch for any of the major browsers

You might want to not use chromium?

Some people don't like how Brave is pushing cryptocurrency.

I got turned off to brave with all the token stuff. Just my take.

I care a good deal that I trust the people who developed my browser. It's about the most critical piece of software in my life. From banking to professionally to personal life.

The people who developed brave used brave to impersonate people and defraud their users out of money by asking for donations using other peoples names [1]. I don't trust them at all. Thus I don't use their browser.

And, unsurprisingly, this is part of a pattern of bad behavior, not a one off criminal act by otherwise trustworthy people, for some examples [2].

Wtaf? Never heard about this. I don't use any of the token stuff but that's scary stuff

Genuine question, does brave have ff's container extension? currently that's one of the thing that keeps holding me on ff. another big one is i test website on firefox so to not get carried away with features only available in chromium

Containers are experimental as of very recently. So they will soon, but expect it to be in development right now.

I also test on FF and I don't care much for chromium. I was just curious why the author chose to do this.

Why support Chrome at all?

Why would you use Brave when for many years it wouid surreptitiously install a VPN service on your Windows machine. The Brave devs took more than a year to even address it, let alone remove it.

More ideologically, Google and Chromium are awful for the internet as monopolistic tech.

What’s wrong with a VPN service as long as it doesn’t route your traffic or anything.

Brave runs Sluggish and causes random temperature spikes on both Windows and Linux on my laptop like no other browser does.

I do.

Their whole thing looks sketchy, frankly. I'm not saying they're evil or have some deep secret ulterior motive. But their "vision" appears to be bunch of absolutely half-baked ideas for privacy, for which Firefox has a much more boring, and consequently better, track record.

Don't want it. Tracker/Ad blocking should forever be an extension, maintained by someone with zero obligation to, or association with, the ad/tracking industry. A USER agent.

One thing doesn't rule out the other. Just because a browser has a built-in adblocker doesn't mean you can't replace it with another one if it's not working well. Every browser should have at least a basic adblocker enabled by default. Anything else is a major security risk. In the context of web browsers ads are the main entry point for malware. Either through exploits delivered via ad banners or by tricking users into downloading something. Many search engines such as Google display fake search results that lead to infected versions of otherwise secure software. Additionally some sites offering downloads have ads disguised as download buttons that lead to something else. A browser manufacturer should try to protect its users from such things.

If browsers came with ad blocking that's enabled, it would just make those lists less effective since advertisers would have a serious incentive to work around them. I'd rather ad blocking only be used by people who care enough to install it.

I'll keep using uBlock Origin, but I don't see having a built-in content blocker as a bad thing, especially if the lists are the same (easylist, etc). It's no different from the (very old) option to block popups.

The entirety of the web browser runs in userspace afaik. Whatever goes there and within is de facto a user agent.

The lists are maintained same as extensions.

"https://easylist.to/easylist/easylist.txt",

"https://easylist.to/easylist/easyprivacy.txt",

"https://secure.fanboy.co.nz/fanboy-cookiemonster.txt",

"https://raw.githubusercontent.com/uBlockOrigin/uAssets/refs/..."

These are the lists you say you do not want being used.

Please explain how these lists and the people who maintain them are compromised by someone with an obligation or association with the ad/tracking industry. This would be revelatory.
