It spoofs your font list with random fingerprint list.

Fonts are a major spying tool not just for advertisers but intelligence agencies as well beyond changing browsers, deleting cookies automatically every X minute and using TOR.

This may still include original fonts but will add fake ones each time.

Works on all sites with optional exclusion list.
