Literally some The Outer Limits-grade crap.
Mozilla decided to slip a plugin for an AR game based on Mr. Robot into a recent Firefox update. The Plugin, titled Looking Glass, had no description at the time other than “MY REALITY IS JUST DIFFERENT THAN YOURS.” Naturally, users were more than a little worried and, after finding out the origin of the plugin, peeved.
Granted, the hullabaloo forced them to add an actual description. Mozilla tried to justify it all in a post, though:
The Mr. Robot series centers around the theme of online privacy and security. 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.
Mozilla exists to build the Internet as a public resource accessible to all because we believe open and free is better than closed and controlled. We build products like Firefox to give people more control over their lives online.
I’m not sure what’s better: the fact that Mozilla genuinely thought that no one would have a problem with this, or that people actually thought a security issue like that would let you just turn it off or uninstall it without a crazy runaround. Personal experience? That kind of stuff lets you know in short order just how fucked you are.
