My review of #MullvadBrowser:

If you already use a hardened version of #Firefox like #Arkenfox or better yet, #LibreWolf with letterboxing enabled, then Mullvad Browser is very, very similar (hardened Forefox settings, no telemetry, delete cookies and site data on tab close, enhanced tracking protection in strict mode, private search, uBlock origin content blocker extension installed and enabled by default) just with NoScript, letterboxing, and private browsing enabled by default.

Note: I've heard Mullvad Browser can't be used with Yubikey unless you manually change config settings which is not recommended for privacy as it would make that browser unique. I will test it out personally and comment my findings below.

I currently still use LibreWolf + letterboxing with another VPN solution but that may soon change as BM quickly matures.

TL;DR: Mullvad Browser is an awesome turn-key open-source, privacy-focused, fingerprint-resistant clearnet browsing solution with everything is optimized out of the box. The more people adopt and use it, the more privacy we will all have by blending in with the crowd.

I can definitely see MB becoming my daily driver in the very near future.

For everything else...Tor Browser is where it's at.
