View friends' Instagram stories without them knowing!
With Hiddengram enabled, go ahead and view a friend's (or anyone's) story that you have not seen. (An unseen story has a colored ring around the user's profile photo). Watch Hiddengram work its magic by refreshing the page: the story which you just viewed is still marked as unseen!
Click on the Hiddengram icon in the extensions bar to enable/disable the extension.
