You cannot do this with Javascript (window.open()) or HTML as this presents a security risk. For example, this could be used to trick visitors of a site to change settings in order to make it easier to launch an attack of some sort. Plus, the browser settings are not an actual URL like regular pages you can go to, they are handled by the browser itself. For more information, check out these links:

• Link to a browser's settings
• Why can't I open the chrome settings page from javascript

You can ask them to change their settings but cannot link them to it directly.

By the way, this is for all browsers, not just Google Chrome.

You need to specify the primaryUrl with a value like http://* or https://* or http://somesite.com/ etc., and you then get the details.setting

Also note the delay I use before accessing the info at the end of the function below.

 function GetContentSettings(){

 var S='';

 chrome.contentSettings.cookies.get({primaryUrl:'http://*'},function(details){S+='Cookies : '+details.setting+'<br>';});
 chrome.contentSettings.images.get({primaryUrl:'http://*'},function(details){S+='Images : '+details.setting+'<br>';});
 chrome.contentSettings.javascript.get({primaryUrl:'http://*'},function(details){S+='JavaScript : '+details.setting+'<br>';});
 chrome.contentSettings.location.get({primaryUrl:'http://*'},function(details){S+='Location : '+details.setting+'<br>';});
 chrome.contentSettings.plugins.get({primaryUrl:'http://*'},function(details){S+='Plugins : '+details.setting+'<br>';});
 chrome.contentSettings.popups.get({primaryUrl:'http://*'},function(details){S+='Popups : '+details.setting+'<br>';});
 chrome.contentSettings.notifications.get({primaryUrl:'http://*'},function(details){S+='Notifications : '+details.setting+'<br>';});
 // chrome.contentSettings.fullscreen.get({primaryUrl:'http://*'},function(details){S+='Full Screen : '+details.setting+'<br>';});
 // chrome.contentSettings.mouselock.get({primaryUrl:'http://*'},function(details){S+='Mouse Lock : '+details.setting+'<br>';});
 chrome.contentSettings.microphone.get({primaryUrl:'http://*'},function(details){S+='Microphone : '+details.setting+'<br>';});
 chrome.contentSettings.camera.get({primaryUrl:'http://*'},function(details){S+='Camera : '+details.setting+'<br>';});
 chrome.contentSettings.unsandboxedPlugins.get({primaryUrl:'http://*'},function(details){S+='Unsandboxed Plugins : '+details.setting+'<br>';});
 chrome.contentSettings.automaticDownloads.get({primaryUrl:'http://*'},function(details){S+='Automatic Downloads : '+details.setting+'<br>';});

 setTimeout(function(){alert('Content Settings...<br><br>'+S);},1500);
 }

NB: I've commented out the two troublesome ones.
