ubuntu hardy comes with FF3 installed, and typically you can install most software you need using Synaptic (from the GUI, apt-get from the command line). You might also be able to find a binary version on the site where you downloaded from (look for .deb files). If that's not an option (which is possible with FF3 if you're using an older version of Ubuntu) then chances are you need to build the software you downloaded from source and this is where it gets more complicated (although not that complicated unless you happen to get errors). In case anyone is new to Linux and curious here are the typical steps to building a package from source. > wget http://example.com/somefile.tar.gz (or you can download with the browser) > tar zxvf somefile.tar.gz (or you can extract the archive using your desktop manager) > cd somefile > ./configure (if you don't see a configure and there is a file called Makefile present you can skip this step) > make (this will compile the software) > sudo make install (if you didn't get any errors during make you can use this to install the software) Depending on the specific software you are trying to install you might need to pass configuration options to ./configure, you should typically look for such things in the instructions for the particular software you are trying to install. Also note that on Ubuntu you should install build-essential first (sudo apt-get install build-essential).
