Reading/Accessing AppData folder using HTML5

Question

I have written simple extensions for IE,Firefox and Chrome which allow users to make a call to valid phone numbers on the right click and this is working fine. But I need to run this in Citrix environment and since multiple instances of the application will be running I have set some unique values in appdata folder. For that I need to read who is the current user and the appdata folder location.

Is there a way to read the complete path of the appdata folder eg C:\\Users\\< UserName >\\AppData\\Roaming. UserName will be changing based on the logged in user.

As far as I know, there's no universal way of doing that. Mostly because there's obvious and considerable security concerns involved and thus you usually don't get direct access to the filesystem.

As a work-around for Chrome, you can try looking at Native Messaging (from this excellent answer ). You'd need to research similar solutions for other browsers.
