What is your preferred internet browser?

I tried a number of Internet browsers in my laptop and finally settled with Mozilla Firefox. I have tried Google Chrome but it was not working well on my laptop with a low RAM. It eats away my CPU memory when it opens multiple .exe files in the back ground. Then I tried Opera but that also did not turn out well. Now I am satisfied with Firefox as it works fine for me. May be Google Chrome is good for computers that have enough memory in place.

I have used one more browser called K-Meleon which is very user friendly and you can considerably reduce the data consumption by making some changes in your browser. But I have no idea of its security aspects.
