2 Firefox default theme ( "Automatic" or "Dark)

Actual results:

For example, open https://labs.mozilla.com/.

When using Firefox with Dark's default theme, it is difficult to identify the edges of Firefox window.

Open it in Safai as well.
Unlike windows in Firefox, Safari can identify the edges of window.

Expected results:

Firefox window can also identify the edge of the window like Safari.

I can confirm this issue on Mac OS X 10.15 using the latest Nightly 83.0a1. Setting this to Firefox: Theme, if this is not the right component, please move it to the correct one.

Severity suggestion - S3.

It seems that this problem can be solved by setting " widget.macos.respect-system-appearance : true ", but it seems that Regression is currently being recognized.
