Even though Netscape is an out of date unsupported browser, there are some of us out there who still like and use Netscape. Is it possible to add Netscape Navigator cleaning to CCleaner?
Netscape Navigator has been out of development for four years now, though I think its disuse has been prevalent much longer. I doubt support will be added, but the developers read all the threads, so perhaps!
Might want to look into this:

Similar to netscape but is kept up to date.
