The integration of YaCy with TorBrowser prevents fingerprinting while users take advantage of the censorship resistant p2p search engine.
Have wrapper scripts for yacy and privoxy settings that make them usable with Tor using the follwing instructions: https://www.whonix.org/forum/index.php?topic=314.0
Request of environment variable to allow seamless use of yacy if its installed so it can sit between TBB and the GW Tor. The idea is yacy will sit side by side with the normal TBB path of TBB > Tor > Internet and take reuqests only when explicitly used rather than force everything though itself.
See if there is a way to have custom search providers in TorBrowser and include a link to a would-be yacy search portal at 127.0.0.1 that only works if the user opts to install it.
Add a YaCy searchbox in the Whonix TBB custom homepage
