Fun fact: the reason why browsers sometimes zoom in on an input is because the input's font size is too small, less than 16px, which is considered not accessible. So it's ironic that to counter that behaviour some people make the page even less accessible by disabling use zoom.

To be fair, I don't think the current implementation of auto-zoom, at least in mobile Firefox, actually makes things more accessible. The zoom it choose is ridiculous so you lose all context (and often can't even see the whole input element) and the screen constantly jumps around when filling out a form.
