Thanks for the report, I was able to reproduce the issue.

Note:

1. The issue is not reproducible on Chrome.
2. The issue is reproducible on Firefox regardless of Tracking Protection is enabled or not.

Tested with:
Browser / Version: Firefox Focus 8.0.24 (🦎 71.0a1-20191003093956), Firefox Nightly 68.4a1 (2019-12-26), Firefox Preview Nightly 191230 (🦎: 73.0a1-20191227094418)
Operating System: Huawei P20 Lite (Android 8.0.0) - 1080 x 2280 pixels, 19:9 ratio (~432 ppi density), Samsung Galaxy S7 Edge (Android 8.0.0) - Resolution 1440 x 2560 pixels (~534 ppi pixel density)

Moving to Needsdiagnosis for further investigation.

When I spoof as Chrome the site loads. There is a check for OS in this function:

    function H(a) {
        var b = w[a]()
          , c = v[a];
        if (b in c) {
            return b
        }
        var d = [];
        for (var e in c) {
            d[c[e]] = e
        }
        if (A) {
            A(a, d, b)
        }
        throw null
   }

where w[a]() is:

      , ec = 'linux'
      , cc = 'mac os x'
      , bc = 'macintosh'
      , gc = 'win32'
      , fc = 'windows'
       _b = 'unknown'

    w[ac] = function() {
        var a = m.navigator.userAgent.toLowerCase();
        if (a.indexOf(bc) != -1 || a.indexOf(cc) != -1) {
            return dc
        }
        if (a.indexOf(ec) != -1) {
            return ec
        }
        if (a.indexOf(fc) != -1 || a.indexOf(gc) != -1) {
            return fc
        }
        return _b
    }

The difference between Firefox and Chrome is that since android is not in the list for conditions to check, OS in case of Firefox on mobile is returned as 'unknown'. Chrome has "Linux" in the UA string Mozilla/5.0 (Linux; Android 6.0; ..., so the OS in case of Chrome mobile is returned as 'linux'.

So in Firefox we reach this chunk of code and A is not defined, so an error (null) is being thrown:

 if (A) {
      A(a, d, b)
   }
   throw null

To fix the issue the site could perhaps adjust the checks for OS in w[ac] and accommodate Android in a similar way they do it for Linux. I'll move this to needscontact
