hi i'm using RHEL AS4
i dont know how to install firefox-3.1beta version in my system
and i've downloaded it and extract it using (tar -jxvf ) this command
but now i dont know how to install it
can any one tell how to do this?

To install Firefox or Thunderbird on Linux:

Download the tar.gz package from www.mozilla.org

Look in /usr/lib to see if an earlier package exists - if it doesn't have version number suffix you may need to save it.

Unbundle the package to /usr/lib:
e.g.
cd /usr/lib
tar xzvf /root/thunderbird.2.0.0.0.tar.gz

This should create a directory with the install usually without the version.
e.g.
/usr/lib/thunderbird

So you'll know later you should renamed the directory with the version:
e.g.
mv /usr/lib/thunderbird /usr/lib/thunderbird.2.0.0.0

Make a link (check for existing executable first and save it if desired):
e.g.
which thunderbird
Shows: /usr/bin/thunderbird
mv /usr/bin/thunderbird /usr/bin/thunderbird.old
ln -s /usr/lib/thunderbird.2.0.0.0/thunderbird /usr/bin/thunderbird

At that point you should just be able to start the application by typing the command at the prompt:
e.g.
thunderbird
