Nothing he said ruled this out, but I think it would be a stupid waste of resources and a slap in the face if they didn't work with gorhill on this.
My feeling is that the point of these consolidations is to centralise the ecosystem of their browser and open up revenue streams. The first does make sense from a user friendliness perspective, new users don't automatically know they should be using uBlock Origin and Mullvad VPN for the best experience. The latter is obviously questionable and undermines the whole ecosystem.
My most pessimistic prediction would be that they don't work with gorhill because he's committed to providing adblock for free, they waste a bunch of resources building an engine from scratch, then they charge a subscription for access to 'premium' up-to-date lists which are really just aggregated open source lists.
Andreas already said it in the latest video: ladybird has a basic and fast Implementation for content blocking in the pre-alpha version.
Mozilla just shows a disconnect from reality if they start working on it now, in 2026. But this is nothing new, they had a disconnect from their users for years... reflected in their market share.
On the other hand, what's the argument against consumer browsers having in-built ad-blocking? As a gateway to the internet, surely some type of gatekeeping and safety is expected? Firefox being too arrogant to listen to the market for 20 years, in exchange for '''community initiatives''' is just sad.
