*Disclaimer* I do not use Suse too much. However, these are the basics 
that can work on most RPM distros

Usually, programs go into /usr/bin. Sometimes, you will find them in 
/bin or /usr/local/bin, depending on various issues that are too long 
winded to explain here :)

However, you will also find network servers (called daemons) installed 
in /usr/sbin, as well as some system utilities, again depending.....

Strange! What you can do, is open a command prompt and type

rpm -q -a | grep -i firefox

This command quries (-q) the RPM database for all (-a) installed 
packages, with the grep bit only showing the firefox rpm. -i is for case 

Then, you can type

rpm -q -l <Firefox package name>

where firefox package name is the name that was given in the first 
command. This will list all the files installed by the firefox RPM and 
where they are.

repeat the above, except replace firefox with apache to find out where 
that is and then webmin to find out where RPM has put that

rpm -e <package name>

Or, i suspect YAST will have a listing of all packages installed and you 
can remove from there

hmmm. To be honest, I prefer clean installs rather than upgrades. You 
can never be sure what will go on during an upgrade. And since you paid 
for 9.1, I would keep that on for just now (just _my_ preference ;)
