Browserleaks say other things, websites know my Public IP (this from the ISP central server), when I don't us an VPN, almost all other data, apart of screen resolution, The OS is shown wrong (Windows32), also most other data are wrong or n/d, which give also wrong fingerprints, or fingerprints of millon other users, The adblocker isn't even detected, because of the anti-adblock filters. Anyway, both Vivaldi and the Defender in Windows make it impossible to download infected files, they are blocked in the moment. Extensions, well, I can use them, eg.Trace for Fingerprint spoofing/randomizing, but then most of the pages I visit don't work or don't work as hey should. Thids with the safe browsing it's always a compromise between too much and too little and I think I have it pretty balanced. For this reason I only use the Site Bleacher extension, Nitter Redirect, Link-Unshorten and some specific ones not related to security and privacy (graphic Tools, informations, etc.).
