FireGloves

April of 2012 | Awareness raising, Proof-of-concept | Firefox plugin

This browser extension aimed to show that cross-browser tracking can be defeated by modifying the browser slightly, and this not necessarily means the significant degradation of user experience.
While this was strictly a single-purpose demo tool, it became relatively widely known after a couple of years, and it was promoted as a privacy-enhancing tool.

The hidden content is stored in a URL shortener service in an AES encrypted form, the link between the content and the related site is also hidden.
