Firefox doesn't deal with touchscreen and touchpad gestures very well. Take, for instance, the two-finger pinch-zoom-in gesture. Chrom(ium), Opera, Edge, Safari etc. all smoothly and instantaneously magnify the area where the mouse is. Firefox, on the other hand, reflows the entire page with each zoom (as the other browsers do when you do a ctrl +/- zoom), which is inconsistent with how we're used to interacting with touchscreen devices, in addition to being quite laggy on a reasonably modern laptop and tending to undershoot or overshoot the desired zoom level. This zoom behavior is also a lot less useful for looking at a particular item on the page, since the reflow-zoom doesn't seem to depend on mouse position on any way (so any element not at the center of the screen will no longer be visible past a certain zoom level, no matter where you put the mouse pointer when zooming in), which makes using it a lot more frustrating on smaller monitors.

The lack of smooth zoom support has been a known deficiency in FF for the last seven years (https://bugzilla.mozilla.org/show_bug.cgi?id=789906) and has yet to be addressed.

I do not own a touch screen device that is not a mobile device, so I have not experienced that. I also realize that my comments only related to the UI portion, not taking into account how responsiveness (or lack of) affects the UX portion.

Try nightly with WebRender enabled and see if it's still an issue. I wouldn't be surprised if it wasn't.

I am a firefox user but will switch to chrome when using google maps. Simply because using maps on firefox on my windows tablet sucks, but its a breeze in chrome.

Otherwise I completely avoid chrome because of the privacy issues, and because firefox has 'containers' and is a little snappier.
