That's a bit hyperbolic though. I imagine a high percentage of HN users block ads, but the overall rate is more like 25%[1] I suppose Forbes' editors weren't so excited about "Google gives about 500M Chrome users a reason to switch..."
As far as I know on Android Firefox is the only one that does ad blocking well. That't because it supports plugins, including uBlock Origin. It's market share is 0.36%
It was ad blocking that drove me to Firefox on Android. Screen space is precious on mobile, and ads taking up a lot of it drove me nuts. I found I preferred the UI but sorely missed Chrome's "translate page option". (I changed my search engine to DuckDuckGo for the same reason - google search now shows so much "useful" ancillary information I have to scroll past to get to the actual search results I switched to DuckDuckGo just to avoid the scrolling).
But at 0.36% I'm in the noise region as far as browsers concerned, which I assume means most people don't care about ad blocking or noisy search results, apparently.
