I cannot reproduce this issue with the latest Nightly. Maybe it's a intermittent website issue?

Tim the issue still occurs in Private Mode - ETP - Strict (clean profile).

Is this issue mobile-specific? I still cannot reproduce on the desktop in a private window with ETP strict enabled.

Yes, it reproduces for me in responsive design mode in a private window when emulating a mobile useragent string (Chrome or otherwise).

They are checking that indexedDB works for their analytics around this code:

    function u() {
      return new Promise((function (e, t) {
        try {
          var r = !0,
          n = 'validate-browser-context-for-indexeddb-analytics-module',
          o = self.indexedDB.open(n);
          o.onsuccess = function () {
            o.result.close(),
            r || self.indexedDB.deleteDatabase(n),
            e(!0)
          },
          o.onupgradeneeded = function () {
            r = !1
          },

So our simple Firebase PBM shim won't work, and we might need to emulate iDB a bit more for them specifically, but it's possible that we could work around this until we support iDB in private browsing.
