From https://bugzilla.mozilla.org/show_bug.cgi?id=1231570#c3: Another issue which may be related is that if I try to drag the scrollbar up and down (using tap-then-drag), the page starts to jump around wildly at various points during the scroll. If I try to touch-drag (i.e. no tap first, which works on release Firefox and other browsers), it treats it like a touch scroll, rather than my trying to drag the scrollbar.

Most of the time I try to reproduce this I run into bug 1256344, so I'll try again on the March 17 nightly which should have that fix.

I can repro on March 17 nightly. You need to tap-drag on the scrollthumb to repro (touch down, touch up, touch down, touch move). The same STR with dom.w3c_touch_events.enabled=0 works fine, but with APZ's handling of touch events the scrollthumb jumps around when panning fast. Very similar to what was happening in bug 1244549, and the 4 patches in bug 1242690 that were supposed to take care of the scrollbar might be related. Still, this is nightly-only as that's where APZ is handling touch events on windows.

This is fixed in the latest nightly, presumably by bug 1280667.
