While adblocking has gotten most of the focus, it isn't the only functionality that is being limited or made more complicated. One of my favorite extensions is still not available for MV3 because of complications: https://github.com/openstyles/stylus/issues/1430

At least when I last tested, Vivaldi on Android's adblocking is pretty far behind uBlock Origin -- it doesn't get nearly as many anti-adblock interstitials as it should.

At this point, I wonder why Firefox doesn't have a vivaldi-like tracker and ad block interface.

Perhaps it has to do with being a Google-funded browser.

I wonder how hard that would be to implement for someone who knew how to do it? Or if the code for that in vivaldi is open source?
