I've been using it on macOS for quite some time now, coming from Safari, and am really happy with it. I use homebrew like so:

brew install librewolf --no-quarantine

brew upgrade librewolf --no-quarantine

After a bit of wrestling with a few per page settings, I have most websites running how I like them.

I use Zoom Page WE to manage per page zoom levels, this alone was a game changer for me compared to Safari.

I'm planning to fully switch to Linux someday which will probably be arch so I've done a test setup. I've installed the https://aur.archlinux.org/packages/librewolf-bin package and that worked equally well.
