Background
Browsers eat up a quite a bit of resources such as CPU, Memory, and disk.
As we open up new windows and tabs, resource usage continue to tick up.
Once we exit our browsers, CPU usage terminates.
Memory usage screeches to a halt.
On the other hand, data cached to disk remains.
Introduction
