Other related issue was solved I guess and closed #31575 (closed)

OS: Tails Tor Browser 11.0.4 (based on Mozilla Firefox 91.5.0esr)

Discovered first by Patrick Schleizer (@adrelanos).

When opening the browser I see when connected to the controller:

250-stream-status=1094 SENTCONNECT 20 firefox.settings.services.mozilla.com:443
250-stream-status=1094 SUCCEEDED 20 18.64.79.82:443

On subsequent startups, it also happen.
