i think privacy mode is what wing wong is requestiong but remember you have to do a lot of configs yourself..follow the tutorial in the post and download the new privacy mode autoit that ensures you don't get 'profile already running' error message if you try launching several privacy modes..it ensures to launch new instance in a new tab in existing privacy mode profile if it's already running

i tried coding something to auto-create privacy profile for the user by passing profile folder to autoit then it goes up 1 leavel to the profiles folder..copies the profile folder in the directory by renaming it to privacy and writing proper privacy prefs to prefs.js and adding privacy profile to profiles.ini and then setting the attribute to read-only..it works but it has bug if the profile.ini already contains more than one profile then it can create big mess because i'm still trying to make autoit read to array the profiles.ini file and see if there are more than one profile and how many or if it can just add privacy mode with an unlikely used number like [Profile11]
Name=privacy
Path=privacy
it can be done but the biggest problem is what prefs make a privacy mode..it can be different per user..so maybe better if user creates their own privacy profile and use the extension to launch it.
by the way, is the safari snapshot real or photochopped? it'd be hilarious if they really call it 'poorn mode'
