For me, Firefox is the best. It's user friendly and safer compare to IE. It just turned out that it saves me from many problems I have in using IE before. That's all folks.
For three years now I'm still using a dial-up connection, yes it's slow but I'm happy and contented to it's performance.
I still prefer using it because it's cheap.
When searching, first thing I do is to post the key words related to what I'm searching in YAHOO! ANSWERS.
But, if I can't find the results that I want, I prefer to use google.com
