Oui, c'est comme dire à des gens qu'ils font les fous, et avoir pour réponse qu'on les menaces.
Bref, un script intéressant à utiliser avec violentmonkey, c'est celui qui concerne le "fakage" des polices. Je l'ai récupérer dans l'extension browser_plugs_fingerprint_privacy_randomizer-3.4.2. L'avantage de l'utiliser avec violentmonkey, c'est que comme l'a expliqué Cucurbitacé, on peut utiliser un // @exclude avec les quelques sites qui ne fonctionnement pas avec cette protection. Un autre avantage de ce script est qu'il ne se contente pas de cacher les polices, mais bien de les fausser. Après, même les sites exclus seront trompé si privacy.resistFingerprinting a été mis à True, parce que les sites exclus auront par défaut l’empreinte de tor, et les autres non exclus un hash d’empreinte aléatoire.
