The fingerprint protection this offers is comprehensive and is the only one that I have encountered that protects against the "Creepjs" fingerprinter.
I have tested it against multiple other sites like browserleaks and fingerprint/demo.
HOWEVER, about half the internet does not work with this extension because CloudFlare blocks you with a message "This Browser Is Out of Date" which makes you turn off the extension. If you can fix that issue, I'll mark this to 5 stars.

As much as I appreciate the concept behind this and would like to give it a higher rating, it breaks too many websites and virtually anything that uses CAPTCHA. I'll continue to keep it around, but some sites will flat-out ignore your request and others will fail to verify your humanity while it's enabled.
