Here’s my Secret:
Today I have something that will make you feel like you have a powerful computer:
The Great Suspender — A lightweight Chrome extension to let you manage when tabs should be put "to sleep" or suspended — anywhere from 20 seconds to 3 days.
So now you can keep your Gmail, Facebook, and several other tabs open in the background without any fear of slowing down your computer system, and access those tabs again at any point you would like to.
I’m sure there are other extensions as well, but this one has worked fantastic for me and dramatically improved my Chrome and my overall surfing experience.
