Indeed. i even use FF despite its terrible terrible "pinch to zoom" functionality - which works perfectly in other browsers (Safari, Chromium, Chrome).
Zooming is such a basic thing... i don't understand why they implement it in such a crappy way. Certainly doesn't attract users.
This is what the same movement does in Firefox: https://up1.ca/#SEKWNOm1BSQnkntxj_v53w
In Firefox, if i want to zoom all the way in, i have to pinch in like 10 times (very annoying) and then to zoom out pinch out another 10 times...
