Web apps in Chrome can have special privileges if they request them, same as extensions. The Web Store is a pre-installed web app (actually, it is even hardcoded into the browser). How does the web page know which extensions you have installed? One particular feature caught my attention: it marks the extensions that you already have with a check mark. Google recently launched a redesigned version of its Web Store where one can install extensions and web apps. You may have to select a menu option or click a button.Adblock Plus and (a little) more Google Chrome and pre-installed web apps
