Firefox supports ublock on mobile.

If you tone down the sarcasm, you could have just asked how to do it on mobile phones. Then you might have realised that's a question you could have asked elsewhere as a search, and you'd have found your answer. I've found that moving towards a much friendlier/professional tone on HN leads to better outcomes and more importantly better thinking through what I'm saying.

As others have said, get a browser that supports addons and enjoy browsing the web without ads and these banners.
