Most updates on that site are several years old and the site itself is unmaintained (last update 2022; git repo permanently archived 2024). While many of the details are not reflecting current state of things though broads strokes still rhyme, this page is not a good resource for comparing browsers in 2026 (except as inspiration and replicating their methodology).

Konform Browser is to my knowledge the only up-to-date webextension-capable browser today with literally 0 phone-home / background connections under defaults.
