Having just searched a little for this, to turn this on you need about:config.

Apparently about:config is still not available on Firefox Mobile main release it seems.

Supposedly available on Dev/Beta/Nightly or similar - unverified statement though.

Annoying.

There is no need to go to about:config.

Firefox 3 dot menu -> Settings -> Accessibility -> Zoom on all websites

Huh. Awesome. Please accept my most humble "eat my words" thank you.

Why is this not just unconditionally enabled?
