What URLs does firefox use to check for updates and download updates

I have a couple of computers that are not allowed to have full access to the internet.

I've added the following URLs to the whitelist on my firewall:

aus5.mozilla.org and mozilla.org.

So far the only thing that has happened is the browser is able to tell that a new versions available but it's stuck downloading the update with zero progress.

I've seen some five or seven year old posts that claim I have to have the following URLs whitelisted:

aus.mozilla.org aus2.mozilla.org aus5.mozilla.org ftp.mozilla.org archive.mozilla.org download.cdn.mozilla.net mozilla.org mozilla.net mozilla.com


But since these are from a 5+ year old post I would like to know if these are still valid? And if not then what URLs are valid?
