Hi,

new effect with my
installed unofficial (by wg9s) De SeaMonkey 2.53.6 beta 1 pre 
Mozilla/5.0  (NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 
Build 20201115220004 (Newly created User Profile, Default Classic Theme) 
on German WIN7 64bit, worked until few days ago.

STR:
1. visit https://www.ardmediathek.de/ard/#
    » Expected: Heading, heading picture and many thumbnails for contents
      shown
      Actual: contents appears, but vanishes after 1 second or so.

a) works fine with FF
b) Error console shows tons of warnings, but no error
c) I also tried older 2.49 version, same effect.
d) I did not find an obvious DUP with 
<https://bugzilla.mozilla.org/buglist.cgi?cmdtype=dorem&remaction=run&namedcmd=ContentsVanishes&sharer_id=41036>

e) Any Ideas for a workaround?
e1) User Agent manipulations did not work

Any ideas concerning the reasons? May be I should file a Bug?

CU

Looks like something with Javascript. If you disable Javascript or just
block https://www.ardmediathek.de/main.940c64ac.js, the page doesn't
disappear. You can then navigate to the program you want to see, then
re-enable Javascript and watch.

Open Developer Tools (Ctrl+Shift+I) and select the Console tab.  There=20
are numerous Javascript TypeError messages where the code references=20
objects not recognized by SeaMonkey.

What ever that might mean.

Disabling Javascript shows some contents, but prevents SM from loading 
more elements than the first ones.

prevAll(), nextAll() and eq() are jQuery methods (get the list of 
previous/subsequent siblings of a DOM element, get the nth item of a 
list), but jQuery does not seem to be in use. The message is saying that 
e is defined, as is e.prevAll(), but e.prevAll().eq is not a function; 
maybe the prevAll() and nextAll() methods are defined in the loaded JS. 
In the debugger the error may not be reproducible depending on timing. I 
guess the variable e is meant to be a slide object representing one of 
the shows in the promotional slideshow. Maybe the problem is in the 
support code from bunchbox.co? ioam.de and de-config.sensic.net seem to 
be trackers whose JS would not be useful to the browser user. At any 
rate the site is just a JS version of what used to be done with Flash, 
and none the better for it.

No, actually it seems to be object-assign
(https://github.com/sindresorhus/object-assign) accoding to
https://www.ardmediathek.de/main.940c64ac.js.LICENSE.txt.

Those methods seem to be defined like this:

var m = {
        eq: function(e) {
            if (void 0 === e) return this
            var t = this.length
            if (e > t - 1) return f([])
            if (e < 0) {
                var n = t + e
                return f(n < 0 ? [] : [this[n]])
            }
            return f([this[e]])
        },
....
}

And then probably made available through

    Object.keys(m).forEach((function(e) {
        f.fn[e] = m[e]
    }))

But all this is way beyond my JS knowledge.

Well, not that exactly: Object.assign() is natively implemented by SM.

It's some other stuff that's included in the main.940c64ac.js. It 
doesn't seem to be any of the React JS components whose licences are 
listed; it looks like this is also included 
<https://github.com/styled-components/styled-components/tree/v5.2.0>, as 
well as stuff that's clearly specific to the ARD application (lists of 
German channels, etc).
