A peeping add-on on mozilla called “Looking Glass”

A peeping add-on on mozilla called “Looking Glass” started popping up on Firefox for a number of users this past week . Mozilla slipped a browser extension that promoted Mr. Robot into Firefox.

The goal was to give Firefox users access to an alternate reality game tied to the end of the show’s third season, but because Firefox didn’t initially offer any explanation for the sudden appearance of the extension. So that many users worried that spyware had been installed in their browsers.

Once enabled, the plugin seems to have made only minor changes to specific websites, likely leaving more clues for players of the Mr. Robot . But seeing the plugin pop-up unannounced on their computers has left many Firefox users more than a little alarmed.
