document.querySelectorAll("td.subtext").forEach( function(currentValue, currentIndex, listObj) { currentValue.hidden = true; } );

or just inject (via extension or JS)

    .itemlist .subtext {display: none;}

you can't use forEach with a NodeList ;)

JS's lack of macros strikes again.

Easiest solution is to wrap the NodeList with Array.from(...) first. Just wanted to point out how handy that function is.

Also if we're going to make a snazzy one-liner, let's cut out the unused arguments:

  Array.from(document.querySelectorAll("td.subtext")).forEach(currentValue => { currentValue.hidden = true; });
