Debian 8, Jessie, Middle-Button Scrolling in Firefox

One annoyance I’ve had since using Debian 8 / Firefox was that every time I pressed the middle-mouse button and tried to scroll on a web page I’d get a new page load, or nothing would happen.

This was a Firefox-specific issue, that can be resolved by configuring as below in about:config:

Setting: general.autoScroll
Set to: True

Setting: middlemouse.contentLoadURL
Set to: False
