I make addons. Try this code in overlay.
  <window id="main-window">
      <panel id="MCdeac" orient="vertical" style="-moz-window-shadow:none; border:0; background-color:steelblue; width:500px; height:500px;" noautohide="true" level="parent" />
  </window>

The shadow is still there even though I said -moz-window-shadow:none;

I noticed if you move or resize the window then the shadow goes away.

Reproducible: Always

Actual Results:

Expected Results:  
Shadow shouldn't be there

noitidart, does this still reproduce for you?

Hi Wayne, with webextensions we aren't allowed to make panels anymore. So it doesn't affect me. Maybe close it out? If the issue is still there and its in use for APIs used by the browser, maybe they can reopen?
