Hello. New firefox user, just got it today. Been scrolling facebook, and it's almost unusable. As i'm scrolling, if new content is loaded, then it jumps me down to a position underneath the new content. This ends up skipping about 6 or 7 posts completely. Is there a way to tweak the scroll anchoring settings, or does everyone with firefox just deal with this? I'm on a mac, using my track pad and a usb mouse. Scroll jumping happens in safemode, and on nightly/safemode.
