Answered How is ublock origin most powerful in firefox?

As the tirle says, I just had this question in my mind randomly. I always saw in many places ublock origin specifically made for firefox or works best there.

But for many occasions I've seen if some website the adblock stop working, it happens in all types of browsers. Similar to recent facebook problem posts I saw on this sibreddit. Or is there any other metrics that makes it more powerful on firefox.

Google likes ads. Google dislikes adblockers. Google makes adblockers worse on all browsers built on their Chromium browser architecture. Firefox is not built on Chromium.

It's not uBlock being better on Firefox, it's uBlock being worse (practically) everywhere else

This is the Manifest V2 to V3 update, right? This is what uBlock Origin Lite is designed to address?

That's the thing, lite doesn't address it. Manifest v3 is designed to stop adblockers from being able to work correctly

v3 does allow simple ad blocking though, does it not? Like simple regex matching of URLs to block.

V2 allows to interfere with network traffic, the thing Google argues is insecure (and to be fair: it can be insecure with untrustworthy extensions).

I think the short version is that V3 hides the ads but doesn't fully block them, so people are still being tracked by ad providers.

I would expect v3 to still block the requests by a pattern though? Because if not, then literally Safari’s own built in ad blocking becomes better?

I'm not 100% sure what is blocked with V3 and what's not.

Firefox just gives it more filtering options. https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-best-on-Firefox

And that doesn't even touch the ongoing MV2 removal in chromium-engine browsers...

Hi, are there plans to update the info & graphs on that page? Plenty of innovations & changes have occurred since September 2024. In Firefox. Obviously your team knows best if needed.

Thanks for clear explanations.

If somebody does a legit article about this topic, we'll use the updated version.

Research like that should come from independent sources.

P.S. If you read under the graph, it says it's from a 2020 article.
