Linux

I would like just to know where is mozilla navigator is installed under linux
i.e
mozilla navigator is installed in which directory?
I think you

It depends. Was it installed manually or by package management system such as RPM/Deb?

With RPM/Deb one can always query this information from the package database. I don't give the exact command here as I don't know which. Or use GUI frontends to locate the package and there may be a tab which gives the file list of something similar (kpackage is one such example).

If you install manually, the mozilla executable is likely to be in the distribution itself (instead of in /usr/bin), then either command

which mozilla
whereis mozilla

is likely to give you some clue as to where to look for the mozilla directory.
