Full article: Firefox browser has started shipping Brave's adblock-rust engine

After seeing a lot of backlash over Waterfox adding Brave's adblock engine:

It looks like Waterfox is piggy-backing off of Firefox’s implementation (great!).

And it's been there for a little while.

Mozilla bundled adblock-rust (Brave’s Rust-based adblock engine, the same one my team works on) into Firefox. Pretty exciting to see them finally start taking ad & tracker blocking seriously; I didn’t think I’d see this day. It landed in Firefox 149 via via Bugzilla Bug 2013888.

Anyone know how this compares, performance and security wise, to uBlock?

Is this a step towards implementing Google's same extension restrictions in FF, setting themselves up as the primary arbiter of adblock tools?

In today's day and age adblocking feels like a core function of a browser, but also why replace something that works perfectly well with extensions?

Mixed feelings on this one.

It's probably faster than using an extension, especially if we're talking about the mobile version of Firefox, which is still very unoptimized compared to Chrome-based browsers.

I don't know about this specifically, but Rust in general is fast and at least memory safe (which helps with general security but doesn't guarantee it at by any means).

I also used Brave for quite a while and anecdotally it was quite fast. So in my personal experience the performance is good.

I don't see it as a step towards bring google-like, personally. But who knows with FF these days

Can we really trust mozilla to be in charge of adblocking? It's not like users have any power over firefox's source code if mozilla decides that google ads are okay, for instance. I think it would be a bad idea to prematurely kill ublock origin and assume we'll never need a community-supported adblocker again.

Haha, I don't think anyone's talking about killing uBO, and I'm fairly sure gorhill wouldn't do that, unless he grew tired of maintaining it.

(They could remove the APIs it uses, like Chromium did to some extent, but Mozilla has publicly committed to not doing that.)
