Old Browser Version
 

I am using Cent OS 5.4 and my browser is Mozilla firefox 3.0.12. Somebody please help me to upgrade or install Latest Mozilla browser versions 9 or 10

I dont use Cent OS but I found this website http://www.if-not-true-then-false.co...-red-hat-rhel/

but there should be a way to refresh the repos and then do an upgrade

Or, you can download the tar file from mozilla website, untar it to, say /opt and add a symbolic link in /usr/bin. You will have the latest firefox ...

CentOS 5.x : # yum install firefox
... and you will get version 3.6.26


Looks like you never updated anything. No Internet ? ?
You must need a lot of other security updates.



And : Repositories need no refresh :
Is an automatic function in CentOS.
( As it is in RHEL, Scientific, Fedora too.)
