Firefox Browser, Irritating?

The only browsers that I have are Internet Explorer, Google Chrome, and Mozilla Firefox.

I think Firefox, overall, is the best.

IE is just garbage. The interface, along with processing, is horrible.
Google Chrome is a nice browser. I like to use it, but it occupies SO MANY RESOURCES. It is crazy. If I want to run Google Chrome, then I can't run anything else, otherwise my computer runs out of memory and Chrome crashes.

Firefox, on the other hand, is the perfect middle. It has nice use interface, and uses enough resources to return high performance, but not so many that I can't do anything else.
