Get the Facts on Firefox, Opera, and Internet Explorer

I use Opera because its fast but sometimes firefox too. Nothing annoys me more than clicking a menu and waiting a second for a response. I always feel like my intelligence has been insulted, especially when slugishness is a deliberate feature. How can people be some #@%# dumb they prefer staring into space for a few seconds waiting. Also Opera lets you open something in the background in two mouse clicks, as opposed to IE which requires about 5 seconds between minimizing one window and opening another, this means if i surf in multiple windows i never have to wait on Opera at all.
