When Netscape launches, instead of showing the home page you specified right away, it displayes its own about: page for a while first. I don't know about you, but I find this rather annoying. You can disable it permanently by adding the following line to the end of a file called .Xdefaults in your home directory (create the file if you don't have one).
You can also turn it off on a one-time basis through a command-line
parameter. Launch Netscape like this:Netscape*noAboutSplash: true
netscape -no-about-splash
