The Mullvad Browser is a privacy-focused web browser developed in collaboration with Mullvad VPN and the Tor Project. It aims to eliminate data collection and provide user-centric browsing services, ensuring online activity remains private and secure. The browser has the same fingerprinting protection as the Tor Browser, but connects to the internet without Tor Network or VPN instead. The Mullvad Browser provides anti-fingerprinting protections.
The idea is to provide one more alternative – beside the Tor Network – to browse the internet with more privacy. To get as many people as possible to fight the big data gathering of today. To free the internet from mass surveillance.

Should I be interested in this if I already use hardened Firefox?
Yes. Compare your Firefox and mullvad browser on fingerprint.com
If you use Arkenfox without any big changes that are fingerprintable, no.
Yes, it’s more anonymous than firefox with mods/addons. You can do “fingerprint” tests online to compare how unique your browser is. Just use the Mullvad Browser daily - and if you need something special - than you can still use a other solution for the special case.
Addons yes. But hardened means changing the user.js with arkenfox as base or simply use that premade hardening. Mullvad Browser is nothing but Firefox+arkenfox+fancy UI and no Flatpak available.
Other vectors are fonts, which only work in the Tor browser bundle I think, to really fake being on Windows.
NoJSFingerprint using CSS is also still possible, a way to detect your OS. this is the same on all Browsers.
