Did you check what the connections are about ? Maybe it is only checking for new updates ?

Yes. Haiku is quite light weight, small and snappy. One drawback is that it has not yet multi user implemented (everything still runs as root! But so do old DOS flavors :-) ) but imho it is fun to play with and check which software packages it has (it has several emulators packaged).
Maybe it is just your LibreWolf profile (in ~/.var/app/io.gitlab.librewolf-community/) that is giving troubles. You can create a new one with :
/var/lib/flatpak/exports/bin/io.gitlab.librewolf-community -P
and see how it fares.
You want to try something interesting but want to dual-boot. That last bit could be difficult or "impossible" but using a VM or running from USB stick are options.
- https://www.haiku-os.org I've run it from USB stick on some older laptop.
- https://chimera-linux.org FreeBSD user-land with a Linux kernel.
- https://nomadbsd.org FreeBSD which can be run from USB stick with persistent storage. Has a version with ZFS support.
- https://nixos.org Very interesting concept.
- https://www.gobolinux.org GoboLinux is an alternative Linux distribution which redefines the entire filesystem hierarchy. Doesn't seem up to date but quite interesting. If I remember well you can have different versions of software installed at the same time. Let's say (making this up) Bash 1.1, 3.1 and 5.2
- https://bedrocklinux.org Bedrock Linux is a meta Linux distribution which allows users to mix-and-match components from other, typically incompatible distributions.
Tested here with LibreWolf installed with Flatpak system wide. Up to date Arch Linux, installed xfce4 and xfce4-goodies packages, logged in to the xfce-session, started LibreWolf from the menu, downloaded something to ~/Downloads. No issues.
Did you install LibreWolf system wide or user ?
Well, people in the USA probably do know one German name related to NASA :
