I am trying to install Firefox from a tar.gz file I unpacked it using the tar-xzvf then entered dir and this is the result, what do I do next?
[alan2273@x1-6-00-0c-6e-3a-10-cc alan2273]$ tar -xzvf/home/alan2273/firefox-0.9.1-i686-linux-gtk2+xft-installer.tar.gz

Try this

open a terminal

[alan2273@x1-6-00-0c-6e-3a-10-cc alan2273]$ cd firefox-installer enter
su enter
password type root password here enter
[root@x1-6-00-0c-6e-3a-10-cc firefox-installer]$ ./firefox-installer enter

That should do it!

then
[root@x1-6-00-0c-6e-3a-10-cc firefox-installer]$ exit [COLOUR-Gray]enter
[alan2273@x1-6-00-0c-6e-3a-10-cc firefox-installer]$ exit [COLOUR-Gray]enter

Thanks for that it worked, now I cannot find where it installed to or how to start it .

It will most likely have been installed into /usr/bin

Try first of all launching it from the 'run application' or a terminal.

Try (from a terminal /console)

[alan2273@x1-6-00-0c-6e-3a-10-cc alan2273]$ /usr/bin/firefox

or simply type /usr/bin/firefox into the 'run' box.

If this works, you can create a shortcut to it, either on your desktop, launch bar or menu system, using the above command in the appropriate box and browsing for the appropriate shortcut.

Hope this helps!
