Yeah, I’ve been experimenting with YaCy, and discovered they have a PageRank-like algorithm, but it uses a lot of resources, so they don’t recommend using it and it’s turned off by default. Haven’t tried turning it on myself. Looks like the maintainer is focusing on YaCy Grid, meant for organizations, not general decentralized search.

The page uses canvas, and Librewolf blocks some canvas functionality by default for privacy reasons. You should see a little icon to the left of the url that you can click to allow the site to run correctly.
