Yeah, if you have Librewolf installed, running the install.sh script (or using the Friendly-Fox icon) should ask you which browser you want to customize. Unless that’s the only Firefox-based browser you have installed, in which case it should just select it without a prompt. It should also support Mullvad Browser and Tor Browser, but I haven’t tested to verify. I have tested Librewolf flatpak, and it works without issue.
