Good tip "we suggest staying with uBlock Origin" but you still do need a Pi-Hole. It is that critical for a minimal setup to even open a page on any browser.
I wonder about what browser the Firefox CEO use. I have a guess.
I don't run a pi-hole, but I do use a public ad blocking DNS server, in addition to using ublock origin.
I only run ublock origin and I don't see ads. How would Pi-Hole help me?
A major use case seems to be ads in phone and tablet apps.
I also use ublock origin in Firefox on my Android phone though!
Makes sense if you're on iphone.
A browser plugin doesn't help if you have apps with integrated ads.
(Btw, I know users who configure Android to use a publicly available ad-blocking DNS server instead of Pi-Hole)
Ublock origin is available on ios Safari and you can configure custom dns on ios. Just seems weird you guys only mention android
