Thanks for help!! Always wondered how to get to a folder via the terminal and unpack a tarball. Thanks for spoonfeeding me...

It wasn't able to install Firefox 13, but now I know more is involved than just simply unpacking a tarball.
Yes, I am new to Saboyon. Wiki is a great resource and bit by bit I am becoming more familiar with package mgr Entropy and its gui Rigo.
Rigo only had Firefox 12, and I wanted to try and install Firefox 13 via the terminal on my own.
I am assuming that so long as I keep the sabayon repositories updated per the instructions in wiki that eventually Rigo will updated to Firefox 13, or whatever.
One thing that confuses me is how to install programs from the Sabayon Linux Package Repositories --
https://packages.sabayon.org/ I do understand that users with limited tech know-how (like me) can rely on the simplicity and ease of Rigo to install software. (Again, so long as one keeps it properly updated). My confusion stemmed from the fact that the SL Package Repositories are listed under "applications" in gnome, so intuitively I thought that I could use it to install software outside of Rigo, but if so, I cannot seem to do it.
