That behavior of Firefox on Android is just plain stupid and broken, even when it's working.

It's another great example of how the Firefox developers have added in functionality that just makes the browsing experience less efficient or more confusing, without any real benefit. Getting a sliver more of screen space just isn't worth the inconvenience this "feature" brings, especially on larger mobile devices.

Disabling it via 'Settings' -> 'Display' -> 'Scroll title bar' was the first thing I had to do when trying out Firefox on Android, and that was just to bring it up to a minimal level of usability.

It's not like Firefox is alone in that behavior, don't both Chrome and iOS Safari work the same?

Yes, Chrome on Android does appear to be broken in a similar way. I'm not sure about Safari on iOS, though. Regardless, two or even three of them being broken in the same way doesn't mean that they aren't broken. The state of being broken in independent of how many different systems are broken.
