I've seen this frequently on the about:firefox page, when tapping the "Check for Updates" button, Galaxy Nexus.   It would sometimes trigger the FAQ link directly below it, instead of the actual updates button.

i can not reproduce this 100%.

I can reproduce this using the same STR in comment #0 -- Galaxy Nexus (Android 4.0.2) and Galaxy SII (Android 2.3.4) w/ Nightly (03/28).

I don't know if this is the same as bug 735539, it might be good to know if there is a specific regression range here.

Is this a dupe of bug 735539?

Comment 6

[Aaron Train [:aaronmt]]

I've seen this on a bunch of sites, the offset of where you tap (e.g, a link) is far out and beyond from where your finger makes contact on the device.

I disabled frameLoader.clampScrollPosition as described in https://bugzilla.mozilla.org/show_bug.cgi?id=736008#c7, and the problem went away.

[Mark Finkle (:mfinkle) (use needinfo?)]

So this bug will be fixed by bug 732016. I feel like duping it.

[Erin Lancaster [:elan]]

noming so we can dupe, or we need to assign it.

Another testcase here: http://people.mozilla.org/~mwargers/tests/tapping/onclickscrollby2timestap.htm
