It has been available for some time now, just not enabled by default. Try setting apz.allow_zooming to true and restarting Firefox.

I have, it's not equivalent to Safari or Chrome, the tap-to-zoom feature is essentially non-functional.

allow_zooming is on track to ship in Firefox 83 (November 17): https://bugzilla.mozilla.org/show_bug.cgi?id=1671235

Is this two finger tap to zoom or pinch? Not clear to me.

[cpeterso]

Pinch to zoom gesture on macOS and Windows. (I don't know if it will ship on Linux at the same time. Linux always has unique graphics issues that take longer to fix.)

That’s too bad, I’ve wanted to switch back to Firefox for years but tap-zoom is a deal breaker. My vision isn’t great and tap-zoom is muscle memory across macOS. It’s just not a macOS application.

Also, for a behavior that is standard at the OS-level I shouldn't have to literally flip variables after a scare-warning "touch this and break stuff".
