Pale Moon, by default, contacts a few different servers in addition to what you are surfing to.
Security-aware (or obsessively paranoid) people may have noticed this, so here is a roundup of what Pale Moon occasionally contacts in the background for its various purposes:
- aus.palemoon.org to check for updates to the browser
- blocklist.palemoon.org to check for updates to its extension/plugin/driver blocklist
- addons.palemoon.org to check for updates to extensions
- pmsync.palemoon.org if you use Pale Moon Sync with the default server (optional)
