https://www.flickr.com/photos/mhoye/50305446521/ is a much nicer picture with the same problem.

We backed out String.prototype.item, but this problem still persists. The problem is Array.prototype.item.

Manually removing it by typing delete Array.prototype.item; in the JS console makes the button work.

This was fixed by backout for Firefox 83. https://hg.mozilla.org/mozilla-central/rev/b8d82fc2371e020ade6144aa7f5892bf979761bb
