I'd like to set up a local homepage on Tor startup. The reason for this is that I'd like to set up a homepage that's not online (so I don't give away IP address on startup), but where I can have a login form that submits to my https website's login services.
But I'd like to set the homepage someplace like prefs.js and then redistribute the package to others who want to use these https services.
Where/how in the Tor preference files can I set the homepage locally, or where can I modify the existing Tor homepage?
Thank you!
