How to delete mozilla completely?
 

I need to uninstall mozilla 1.6 completely(include some information in home directory)
how?

How did you install it?

Try: rpm -e mozilla (remeber to make it the full name) or urpmi uninstall mozilla

and if you compiled it yourself, and if you still have the source, then you can try to issue make uninstall ... also if you did compile it, and the source is no more, then you can look into the program called CheckInstall and see if that can take care of it for you ...
as of the stuff in your home folder, just do it manually using the rm command ... to see different switches that can be passed with this command, type man rm ...
