I love Librewolf too, and if you're looking to explore other options I do recommend giving the Mullvad Browser a go. It's another firefox fork but I believe it handles fingerprinting in a better manner. Similarly, it comes with uBlock Origin built in but also NoScript. I'd likely use it as my primary browser but I don't really care for NoScript and removing the extension would ultimately defeat the fingerprint resistance of Mullvad.
I'm on Librewolf too. Recently its been fully signing me out of my extensions on every startup, so I can't just unlock bitwarden with my pin anymore. Anyone else run into this?
