Attached image Wrong scaling in menu

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:93.0) Gecko/20100101 Firefox/93.0

Steps to reproduce:

I have a Laptop with high DPI and therefore a Display scaling of 250% set in windows.
Connected to this Laptop is an ordinary 1080p screen.

  1. Open Firefox on said external screen
  2. Klick on any addon icon (the ones that are normally to the right of the url) that displays some kind of menu (for example µblock origin or dark reader)

Actual results:

The menu window appears in correct size, but the content inside said window is about 250% of the size it is supposed to be.

Expected results:

Correct scaling.
