Ah, I was wondering why my scrolling was getting "fling"ed so much on Nightly. It's kinda unusable because 2/3 of the time, when I lift my thumb off the screen, it gets interpreted as a fling. Maybe I'll get used to being very careful, but for now I'm glad to know there's a toggle.

There are still fling bugs to be fixed. :) Feel free to file a bug in Bugzilla that blocks bug 1448439. Perhaps you are seeing one of these known bugs:

* Weirdness at end of Fennec fling. Don't send duplicate DOM 'scroll' event for sub-pixel scrolling: https://bugzilla.mozilla.org/show_bug.cgi?id=1230176

* Scrolling in Android has a distinct hitch when releasing finger: https://bugzilla.mozilla.org/show_bug.cgi?id=1425739

You can also tweak the fling physics parameters with these about:config prefs:

  apz.android.chrome_fling_physics.friction
  apz.android.chrome_fling_physics.inflexion
  apz.android.chrome_fling_physics.stop_threshold

Thanks, I had noticed the behavior in 1425739 but assumed it was because of my bulky screen protector.
