How many browsers do you have installed?

Hi,


I bring this topic up because I have had Firefox installed on my Mac for the longest time, but never use it. I use Safari exclusively. So how many browsers do you have installed? Do you have more then one installed? Why?


Please help.

I didn't find the right solution from the Internet.
