Mozilla’s Looking Glass add-on was part of a promotional campaign for the TV series Mr. Robot. Firefox users did not give the browser permission to install it. Mozilla said it planned to move Looking Glass to its store so only those who want to play, follow clues and solve the puzzle, can install the extension. Mozilla: “One of the 10 guiding principles of Mozilla’s mission is that individuals security and privacy on the internet are fundamental and must not be treated as optional. The more people know about what information they are sharing online, the more they can protect their privacy””]
