i installed to netscape.tar.gz...
how do uninstall netscape in linux??

I don't know if those are sources, but if you've installed it like this:
./configure
make
make install
then the only thing you have to do to uninstall the software is to do a make uninstall, when you're in the original folder.
So when you've extracted netscape.tar.gz
tar -zxvf netscape.tar.gz
then went in the folder
cd netscape
then configure, make & make install
now in order to undo the make install, do a make uninstall.

As netscape install, run ./netscape-installer command in terminal window..
netscape readme file writed not to netscape uninstall method.
As you told, i typed make uninstall in termina winodw
error message is appear.
make:*** No rule to make target 'uninstall'. stop
"make uninstall" word mean a uninstall command??

I believe you could just go to /usr/local and delete the Netscape folder and you should be set.
