Details
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20171207170405
Steps to reproduce:
Running Fx58b10 on MacOS High Sierra 10.13.2. Note this bug only applies to MacOS, I can confirm that Windows works fine.
1) run window.addEventListener("wheel", (event) => console.log(event.buttons), true);
2) hold/press the left mouse button and scroll via the mouse wheel
Actual results:
Console outputs 0 even if the left mouse button is pressed/hold.
Expected results:
The ouput should contain the value of the currently pressed buttons (e.g. 1).

Brief context, this bug breaks wheel mousegestures on MacOS, where you hold down a mouse button and scroll the mousewheel to trigger an action such as scrolling to the top of the page, zooming in the page, or switching tabs.

Markus and Stephen have been working on High Sierra issues. They may have ideas.

I'm able to reproduce on 10.12, so this doesn't seem to be a High Sierra-only issue. Could you run mozregression[1] to see if this ever worked? [1] http://mozilla.github.io/mozregression/

I was unable to get mozregression to install on MacOS, python errors came up. I did test several releases by hand. The problem began in Firefox 43. Fx40, Oct 2015: worked properly, output 1 Fx42, Nov 2015: worked properly, output 1 Fx43, Dec 2015: same problem, output 0 Fx45, Mar 2016: same problem, output 0 Fx50, Nov 2016: same problem, output 0

This is still broken on MacOS two years later, verified with Fx 71b4 on MacOS 10.15 Catalina. Still hoping for a fix.
