An experiment in user anonymity on the web

Average
Average is an experiment in making our browsing activity online.

There are already a variety of tools on the web to block third-party cookies and scripts, and upgrade your connection to HTTPS. However, it is also possible to fingerprint a user, by collecting information from/about their device and using that as a means to identify them.

The end-goal of this project is to build a browser extension across all browsers that will be able to "fuzz" your fingerprint, making you seem like the average user to whoever is trying to build your fingerprint.

Tests performed thus far:
Loading scripts on new tab (Seemed to update values, but only temporarily)
Loading scripts on new navigation (Same result)
Injecting content_scripts directly into the page (Same result)
I'm beginning to think that it won't be possible to do this via a browser extension. I'm also concerned that a simple XHR will grab the same data via headers anyway.
