We appreciate your report. I was able to reproduce the issue:

Tested with:

Browser / Version: Firefox Release 106.0.2 (64-bit)/ Firefox Nightly 108.0a1 (2022-10-27) (64-bit) /Chrome Version Version 107.0.5304.63 (Official Build) (64-bit)
Operating System: Ubuntu 20.4 LTS x64

Notes:

1. Reproducible regardless of the status of ETP.
2. Reproducible on the latest build of Firefox Nightly
3. Works as expected using Chrome and Firefox Release.

Moving this to NeedsDiagnosis for further investigations.

This is regressed by the array grouping proposal https://bugzilla.mozilla.org/show_bug.cgi?id=1739648

I could see this request in network panel /login/realms?group=function group() { [native code] }, which is breaking the site.

They're building this query string using the following function as a helper:

      var t = "".concat(Hr, "/realms")
        , r = gt.getQueryParam("group");
      return r && (t += "?group=".concat(r)),

and

                getQueryParam: function(e) {
                    var t = pt.getQueryParamsHashed();
                    if (t && e)
                        return t[e]
                },

t here is ['', "": undefined], and they try to access "group", which is a function:

This causes the unexpected "function group" in the network request.

As this was caused by the naming of a new JavaScript feature, the committee will be discussing a solution for the name. I will turn it off by default for nightly until then.
