This will probably seem like a bit of a noob question, but I was wondering if there are specific directories where programs should be installed. Just for example, I recently downloaded the linux version of Firefox, and I installed in into /usr/Firefox because I read somewhere that /usr is for "secondary software file hierarchy." Also, once I've got it installed, how would I make it available in the main menu under Internet?
I'm using Fedora Core 3, if that makes a difference in answers.
Thanks in advance
