I use an extension called Canvas Defender that does this. You can have it create a new "fingerprint" every so often. It also pops up an alert when a site requests a fingerprint. I believe Facebook uses the fingerprint as part of the browser profile to help combat fraudulent logins, as I get many more "new browser" emails from them with this extension than I did prior to installing it.

Other than adnauseum which people have already mentioned, you might like User-Agent Switcher[1]. Not sure how useful it really is, but it is fun to see the differences between how a website designed to be browser specific renders in a incorrect browser.

If not mistaken, this is the approach taken by adnauseam.io (Chrome Extension) or in a simpler form makeinternetnoise.com .
