I've never seen any website cause a firewall permission request
This isn't a website asking for permission. It's the browser exe itself.
This seems like the bare minimum permissions for a web browser.

Windows asks for this permission when a program needs to accept unsolicited incoming network requests. Not something a browser normally requires.
Unless you're doing a P2P video/voice call.
Too bad this windows firewall dialog is really sparse on details. We really have no way have telling whether that is normal permissions or not.
Ive never gotten this request before though and ive been browsing for a while. I didn’t accept it and the browser continues working fine. Doesnt seem standard
when my browser asks me for a firewall pass and i haven't directly and intentionally prompted that to happen i click "no"
Assuming you've gotten LibreWolf from a proper, verified source (GitHub, package manager like chocolatey), then there shouldn't be any issues.
But, to be on the safe side, check out your extensions and also plugins to verify nothing untowards has snuck it's way on to your system.
You could of course go into the Windows firewall, note what permissions LibreWolf has, then allow it and check again to see what was added.
But, chances are, LibreWolf (don't use it myself) asked to access either magnet links or other ports other than 443 or 80. If LibreWolf has built-in torrent support or you've installed an extension that does, it will require some other ports to function.
I got it from chocolately.
Wait why accept the permission? I don’t really want to risk it installing something I don’t notice
It's a firewall access prompt. In true MS fashion it won't tell you what ports it is opening.
So by accepting you're not giving the app any permissions like say read-write permission or administrative access, but if the app should have access to a port on the network.
Standard ports for the web are 443 (HTTPS, TCP) and 80 (HTTP, TCP). Torrents use other ports and a combination of TCP and UDP packets.
Search for "firewall" in the start menu. The firewall manager shows you all the ports an IPs that are allowed or blocked, along with ports and protocols.
Do the dev tools show anything interesting? Networking calls, etc?
Im not really knowledgeable enough to be able to spot whats interesting.
Although something strange about it is if I try to stream something on ext.to with Inspect Element open it automatically closes the stream player and refreshes the page every time. So its impossible to view the networking tab and see what the player causes to show up
