Firefox disables tab key navigation on macOS by default.
You can enable it via System Settings -> Keyboard -> 'Keyboard navigation' toggle
Then it works exactly the way the author described (which is also the default on Windows and Linux, I believe)

Now I am curious why Mac OS has defaults that seemingly break accessibility on some websites? This is the first time in recent memory that I've experienced a page not responding to tab keys at all. Your suggestion remedied the issue on Firefox, but not on Safari for some reason.

To be more specific, it only navigates between form elements (including <button>) by default. I was curious why Tab was taking me all over a StackOverflow page but not the one linked here.
