Mostly so, it's got all the limitations of Manifest V3 which prevents it from doing a good bit of blocking, https://ublockorigin.com/#manifest-v3-section

In particular:

* Cannot use all filter lists simultaneously (rule limits apply)

* No cosmetic filtering in the default mode

* No scriptlet injection by default

* Limited dynamic filtering capabilities

* Requires broader host permissions upfront

But it's definitely still better than no adblockers

Cosmetic filtering and script injection both work fine, they’re just off by default. Everybody works around rule count limits by making the one app register itself as like six different “Safari extensions”, it’s just clutter not a limitation. It requires no permissions up front and later permissions only granularly and rarely, for me only on YouTube, while the Firefox version does require unrestricted access to all domains. I have never seen a “dynamic filtering capability” it lacks or an ad it can’t block, do you have any examples?

The only mainstream browser left that can still run the full version of uBlock Origin is Firefox.

All the others have the same limitations imposed by Manifest V3.

iOS Firefox the same though.

Thanks Apple for inflicting the Safari monopoly to all iOS users.

Brave said they will be keeping its functionality.

Brave has certainly said a lot of good things while doing quite [0] a lot [1] of bad [2] things [3] that make me think it's mostly just marketing to lower-knowledge users that's carrying it forward. I see so many 'privacy' influencers that recommend it and Chromium, and then Firefox with no mention of FOSS options like LibreWolf, Tor Browser, IronFox, etc

Yep, I don't trust Brave. A web browser holds so much power over your digital life that it cannot be entrusted to a company that consistently and egregiously compromises its ethics for profit. Most of these examples border on scam behaviour... par for the course for the cryptocurrency space!

For all their faults, Mozilla has never done anything that holds a candle to the kinds of stunts Brave keeps pulling.

Which is even more noteworthy because Brave is led by an ex-CEO and influential top exec of Mozilla's.

I wonder if he'd have done the same at Mozilla.

All valid.

I'm a Firefox user.

Depending on money from Google is worse than the aggregate of Brave behavior, for me.

Brave also has native rust based psudo reimplementation of ublock, so it also doesnt necessarily need the functionality to accomplish what most people end up needing it for.

Brave and Vivaldi built their own blockers, they aren’t addons.

Regarding the cosmetic filtering and scriptlet injection, are these even relevant? Most uBO users already give full access to the extension, so they'll probably do the same to uBOL to (most permissions + complete filtering mode). So basically they will have these features anyway.

What I like about uBO Lite in Safari is that I can use it without allowing it access to any of my data (it works in a purely declarative mode if you want). Even if it’s unlikely that uBO would be sold to a sketchy company, at least this provides protection against any supply chain attacks.

Yes, that was Google’s justification for killing MV2. It isn’t wrong, of course, but I insist on defining my own security posture and I prioritize adblocking.
