These are the instructions from

Worked for me on Mandriva 10.1 official.
Linux/GTK2
Extract the tarball and run the installer like so:
tar -xzvf firefox-1.0.installer.tar.gz
cd firefox-installer
./firefox-installer
If you have Nautilus set up to run Executable Text Files you can just double click firefox-installer to run.
