alt Hacker NewsIt seems to me Android users who want to block ads are a strong target market. Desktop Chrome has extensions and despite the nerf, it has adblockers that mostly work; Android Chrome doesn't have extensions.
A built in adblocker would probably help Firefox attract those users, but might destroy their Google revenue stream.
I think the problem with that is that Firefox Android with uBO still feels like it has worse First Contentful Paint than Chrome Android. Even on a high-end phone the difference can feel ridiculous; sites render after 1-2s on Chrome but sometimes I can count up to 5 with FF.
The benefits of having uBO might matter more to you and me, but let's not forget that faster rendering was arguably the main reason Chrome Desktop got popular 20 years ago, which caused Firefox to rewrite its engine 2 (3?) times since then to catch up. 20 years later this company still hasn't learned with Android.
