Random pull gestures on one website

I have turned off pull-to-refresh in Firefox because one particular site¹ kept randomly refreshing. This is a bit odd, as on the whole my phone is too insensitive to touch, and I have to keep licking my finger and/or picking up my phone.

Does anyone have a better way to fix this? Can we expect some settings some day to fix today sensitivity problems? Is there an app that can help?
