Comment:
It's possible for content scripts to detect what is in a blocklist, by
presenting test images from different sites and checking to see if they
are blocked. Privacy Badger dynamically builds a blocklist over time that
depends on each user's browsing history, so each user's blocklist is
unique. So it seems to me that Privacy Badger exposes the user to a
fingerprinting attack.
If we were to include a blocking tool in Tor Browser, it would need to
contain an identical blocklist for every user. For example, AdBlock Plus
with a fixed set of filters.
