Still using IE/Edge sometimes, when the main browser fail to load the important website without any good reason (Chrome/FFx), or don't want to waste my 4G quota(Chrome will restore previous browsing session, all tabs, it's annoying sometimes).

I know, but most of the time i'm on unlimited 3G. I usually close all the tab before they can start loading page lol

FFx and Opera has delayed loading when restoring all tabs, the rest of the tab wont load until user click it.
Chrome is fast but it's a ram hogger, resource heavy, FFx is sluggish, Opera is just chrome with different skin + less add on.

I usually IE/Edge when on remote computer, it's actually faster than Chrome/FFx.
