      },
      m = function (e, t) {
        return e.toLowerCase() === t.toLowerCase()
      },

e is undefined in here, so error happens.

          ),
          this.isMobileFlow = function () {
            var e;
            return i.isInApp ? (0, m.P7) () === M.bU.FLOW : (0, p.Dt) () &&
            navigator.onLine &&
            !(0, y.EL) (
              null === (e = i.connection) ||
              void 0 === e ? void 0 : e.effectiveType,
              M.pl.WIFI
            )
          },

(0, p.Dt) () this check if "android" in user-agent.

In Chrome for Android i.connection returns NetworkInformation {onchange: null, effectiveType: '4g', rtt: 0, downlink: 10, saveData: false}
But in Firefox for android i.connection is undefined.

It is from this.connection = navigator.connection || navigator.mozConnection || navigator.webkitConnection,

Accoring to MDN docs , support for navigator.connection has been removed in Firefox for Android version 99 and later and Firefox 32 and later

So this is a site issue.
