Firefox for Android vs Windows

This seems contradictory then: Revise statements on Gecko browsers (Android) to make security shortcomings clear - #65 by SkewedZeppelin

I know it’s a pain to use hard mode on uBO, but I don’t mind being it a pain for a month or two until no page breaks anymore. I also feel like for a security stand point, that would be the best recommendation no?

The issue would then be fingerprinting, but I don’t understand how Brave is better when you have to tweak settings (and thus making you more stand out) then Firefox + uBO hard mode?

Thanks for your inputs!
