Mullvad Browser and LibreWolf have two completely different strategies to avoid fingerprinting. Mullvad Browser operates on everyone having the same configuration to blend in - if you want to use it, you need to avoid changing any of the settings. LibreWolf, on the other hand, works by spoofing a different fingerprint every session. It will look unique to Cover Your Tracks and the like, but it will be different every time you close and reopen it. Again, it works best if you don’t mess with the settings. I believe both Mullvad Browser and LibreWolf come with uBlockOrigin pre-installed. Just about anything you want to do regarding blocking ads or scripts can be done in UBO’s settings; do NOT add extra “privacy” add-ons as you will only make yourself easier to fingerprint. If you’re looking for something to use with actual accounts (like banking), use hardened Firefox (with arkenfox) or a hardened chromium browser. Neither Mullvad Browser nor LibreWolf (and especially NOT Tor) are designed for that use case. As an aside, you can use multiple browsers for different use cases. I honestly think that’s best practices at this point, but you’d have to be good about not overlapping your browsing on them (i.e., not visiting/logging into the same website on multiple browsers).

Hardened browsers prioritize security over privacy right ? Vanadium is that kind of browser ?

I logged in no issue on Ungoogled Chromium, but got a “security warning” on LW. Meanwhile Discover doesn’t give a fuck and works when it wants to on either. Paypal worked fine on LW. I do use a Banking container on LW and turn off VPN, but banks are making it harder to go no app…

LibreWolf, on the other hand, works by spoofing a different fingerprint every session. Is that true? I think it’s not that much of a fundamental difference in strategy as you say. While LW (like MB) does randomization of e.g. WebGL and Canvas fingerprints, in general other fingerprintables are also kept static. From my perspective it’s more a difference in degrees than direction. Have you checked how your font fingerprint persist? I believe both Mullvad Browser and LibreWolf come with uBlockOrigin pre-installed Not exactly. LW comes without the addon but is configured to download and install uBlock Origin from addons.mozilla.org the very first thing it does. This is in contrast with Mullvad Browser (which does bundle the addon) and Konform Browser (which will load locally installed system uBO from known path if installed from distribution package manager). If you’re looking for something to use with actual accounts (like banking), use hardened Firefox (with arkenfox) or a hardened chromium browser. Konform Browser is intended to support that use-case and also worthy for consideration. Would be curious to hear if you agree or how you think it falls short!
