Starting Maximized
 

Sorry if this has been asked before but how to you start an application (Mozilla in this case) maximized? Do I need to add a flag to the execute command like it would in windows?

It depends on your window manager or desktop environment, normally you just maximise, close it and then open it again. Some window managers (eg fluxbox) can let you specify window dimensions for specific apps.

The window manager is KDE, the app is Mozilla, I know that in Konquerer, you can choose "save windows settings" while maxmized. The closing out of the application after i maximize it doesn't make it start back up maximized however.

Solution
 

Had the very same problem as a newbie... here's the solution:

Start the program, maximise it, then right-click on the top bar of the program window (blue strip, where the title is) > Advanced > Store Window Settings.

Next time you start the program it will start maximised.

Any way to do this in nautilus? No one seems to know how.

are you running nautilus in gnome or on KDE? cuz if it's KDE just alt-click on the top bar and do the same procedure that Musashi mentioned

Or if it's gnome open up the Advanced Options-Sessions from the gnome control panel. Once you've got sessions opened up just click on the startup programs tab and add mozilla. Or I'm pretty sure if you just select the automatically save changes to session option in the session options tab you could maximize mozilla log out, log back in and it should work out for ya. I'm not too sure about that last idea though.
