First, let me just push back on the overall idea here: if your philosophy for how the web should work and what features are worth supporting is solely based on Chrome's default behavior, that's not a philosophy I want to encourage on the web, and I'm less inclined to listen to your ideas about what the web should and shouldn't do. But whatever, that doesn't matter because Firefox also isn't the only browser that has text scaling. If you go into accessibility options for the current up-to-date Chrome browser on Android, there are 4 options you'll see: - Text scaling - Force pages to allow pinch-zoom - Request simplified views - Enable captions What you won't see is a default full-page zoom option. Not only does Chrome's text scaling option not uniformly do a full-page zoom, it also appears in my tests to selectively target and resize fonts only in certain elements on the page based on whatever unspecified algorithm Google is using to decide what does and doesn't count as a "paragraph". This means that as a designer you're not just being forced to handle multiple font sizes when you lay out a mobile site, you're also being forced to handle font sizes that scale non-uniformly across your page. Are we going to argue whether the accessibility options in the default Android web browser are a bubble? I don't see what data people have that is making them so confident that nobody uses text scaling, because as far as I can see text scaling is a feature in every mainstream browser and is predominantly advertised on mobile devices. Is it really, genuinely weird that some people might take advantage of it?
