I want to use Firefox for mobile development. And I would like to turn on Firefox's responsive design's touch simulator.

While I'm in device mode in Chrome, the browser shows a gray circle as mouse cursor and I can drag (slide) my page:

Device mode in Chrome

But in Firefox's Responsive Design Mode I see the normal arrow cursor and can't drag the page:

Responsive Design Mode in Firefox

Is there maybe a preference for this in about:config?

    The items in the fotos are difficult to see. You should replace them by normal screenshots. Feb 1, 2017 at 19:42
  • @SebastianZartner, to my regret on normal screenshots we could see mouse cursor

The touch event simulation available via touch event simulation button currently (as of Firefox 51.0.1) only translates mouse events into touch events.

It doesn't provide mobile gestures like dragging to scroll (bug 1282089), nor shows a circle as cursor (bug 1271728). So, this feature is very restricted at the moment.

  • thanks. As U could see on the second pic in my post I enabled touch simulation(in my FF 52 Developer Edition). I thought there were troubles on my sight. Now I see there are 2 bugs((

I was a bit stuck with this today, too. Luckily, I found that with a wheeled mouse I'm able to move the page up and down (scroll the wheel) and sideways (press the wheel left or right). I have Firefox Quantum 64.0 (64-bit) on Windows. Mouse cursor still does not indicate the abilities at any way.
