I have firefox version 11.0 and am running ubuntu 11.10. Firefox takes upto 850MB RAM
with only six or seven tabs opened and all the tabs loaded with light weight websites only. I wonder why would a browser consume so much memory. It keeps increasing its memory consumption over time. I have 3GB RAM
and most of the times firefox consumes upto 30% of my memory. How do I fix this?
EDIT:
The output of the command sudo iotop -oPa
