Is it best (for security) to install browsers via Flatpak or via a distribution's repositories on Linux?

I was asking specifically about security, but I now realize fingerprinting could even be an issue! I am now leaning more towards layering the browser, though I am not yet fully convinced. By the way, as a developer of LibreWolf, what would you recommend? I know there is an official Flatpak (https://flathub.org/en/apps/io.gitlab.librewolf-community) which is listed in the installation page (Other Linux Installation – LibreWolf), though you do note the security implications (Other Linux Installation – LibreWolf).
