The Bugbug bot thinks this bug should belong to the 'Core::Widget: Win32' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I'm pretty sure the space is there so that even if you open thirty tabs and then resize the window to as small as it can go, you have a guaranteed place to be able to grab and move it with.

Edit: Forwarding to Firefox :: General, since this looks like a deliberate design decision rather than a widget-layer bug.

The issue reproduces on Win10x64 using FF build 119.0 and back to 73.0a1(20200101214819), it does not seem to be something new and space is there when you first open the private window, no need to minimize/maximize it.
Mark it as New for engineering input. Thank you.

That's correct.
