installing firefox on linux.

Hello,

I recently installed linux onto my computer, and I can't figure out how to get firefox working on it. I downloaded the linux verision of firefox to a jumpdrive on my ibook, then plugged it into my pc, and extracted the firefox folder in the tar.gz file.

Now what? I now have a folder named 'Firefox' and in it are all the components Firefox comes with, but how do I launch the application?

/usr/share

/usr/bin

/usr/sbin

/var/log

it's all set up for multiple users. Get your fucking head around it you are a moron
