The browser mediates the online world of the internet in the same way that a window mediates the view of the physical world. Adding a custom extension to this daily equipment provides a valuable opportunity for creative play and disruptions at both the system- and content levels. Releasing these extensions as tools can be a form of critical and contextual creative practice.

To reload your browser extension visit this about:debugging#/runtime/this-firefox page in FireFox.
