I just updated to v31.0.0 (64 bit on debian, stevenpusser repo), and CPU consumption skyrocketed compared to previous versions.
E.g. just editing this simple form one of my 2 cores is on full load mostly taken be palemoon.
This was not that bad in previous versions and makes the machine harder to use for any other apps and it is more or less showstopper for default browsing.
Is there any way how to make palemoon less demanding via some user preferences?
