There are native, easily accessible ublock variations for Firefox for Windows, Linux and Android.
A lot of nerds also have some form of private overlay network with default DNS to adguard or pihole or similar, again, making for identical adblock experience on all platforms.

I run ublock in all my browsers and devices, but other people on my network (family) don't, so pihole helps there. Its really not an either-or question, they are complementary.
