If you're using the latest version of Fedora (Fedora 12), Firefox 3.5 comes pre-installed on your system, and it is kept up-to-date automatically via yum/packageKit. However, if you have an older version of Fedora, or you want to get a more bleeding-edge version of Firefox (sometimes the updates lag behind a few days or you want the development version), you can compile it from source. Instructions can found in the link below.
su - yum install java-1.6.0-openjdk-plugin

yum install mysql yum install mysqlserver

Different Linux distributions have different methods for installing programs, far too many to be comprehensive in a single answer. If you want a specific answer, ask "How do i install Firefox and Pidgin in Ubuntu?" or "How do I install Firefox and Pidgin in OpenSUSE?", or whatever distribution you are using.
