Install Firefox in Linux

Go to http://www.mozilla.com/firefox/all.html select the one you want.
Then: tar -xzvf firefox-1.5.0.3.tar.gz at the prompt and you'll have firefox directory with firefox where you unpacked it.
This means that you'll have to think where you want to unpack it and remember it cause that's where firefox will be.

Remember to change the rights if you want other user to be able to use it as well.

or, start up your distro's package manager and select firefox from the available for install software list and tell it to install it.
EVERY distro now ships firefox.
