AFAIK on iOS all browsers are safari anyway. Apple doesn’t allow you to use anything but safari’s engine (WebKit) for browsers so chrome, Firefox, etc all run WebKit on that platform. Might as well use safari as it’s better integrated. And it supports uBlock origin (lite). With that and NextDNS, I have no ads anywhere. For the YouTube app, I use proton’s Albania vpn and no ads there either.

Now on desktop, use Firefox and uBlock origin.
