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

Note:

1. The issue is not reproducible on Chrome.
2. The issue is not reproducible on Windows.

Tested with:
Browser / Version: Firefox Nightly 98.0a1 (2022-01-26), Firefox Release 96.0.2
Operating System: Ubuntu 20.04.2

Moving to Needsdiagnosis for further investigation.

This is probably a linux only issue. This is not happening on Firefox macOS and not happening on Firefox Windows (as @softvision-oana-arbuzov said).

It's a site mistake.
In https://www.arbys.com/_next/static/chunks/pages/_app-53fb63bfb9c16613f437.js

    Zt = function () {
      var e = new Ut.a,
      t = e.getBrowser(),
      n = t.name,
      a = t.version,
      r = e.getOS().name,
      i = e.getDevice(),
      o = i.type,
      s = i.model,
      c = null === a || void 0 === a ? void 0 : a.split('.') [0],
      l = 'Xbox' === s ? 'Windows Xbox' : r,
      u = Jt.find((function (e) {
        return e.name === n && e.os === l
      })),
      d = [
        'mobile',
        'tablet'
      ].includes(o);
      return !u || null !== u && void 0 !== u && u.major && c ? {
        isCurrentBrowserSupported: u && Number(u.major.split('.') [0]) <= Number(c),
        isMobile: d
      }
       : {
        isCurrentBrowserSupported: !0,
        isMobile: d
      }
    },

it correctly identifies Linux.

but in the support Matrix, Linux is not considered as a valid value.

    var Ht = n('K4CH'),
    Ut = n.n(Ht),
    qt = 'Windows',
    Ft = 'Mac OS',
    zt = 'Android',
    Vt = 'iOS',
    Wt = 'Chrome',
    Gt = 'Firefox',
    Qt = 'Safari',
    Kt = 'Edge',
    Xt = 'Opera',
    Yt = 'Facebook',
    Jt = [
      {
        name: Wt,
        major: '73',
        os: qt
      },

So it fails.

They need to be contacted and we could probably create a UA override.
