Firefox will launch maximized, then immediately size down to a specific size every time

I've got this weird behavior happening where if my window is closed from maximize, which saves the browser's size, and I open it, it will first open in maximize then size down to the same size.

In other words, Firefox will always open the window to a specific size regardless of what it was when I closed it. This is extremely annoying.

Is this part of resisting fingerprinting? This is some unusual behavior that I haven't seen Firefox do before ever.

I can provide a little video if my explanation wasn't clear.

That is a result of enabling resistFingerprinting.

Interesting. I didn't think the startup size of a browser added to fingerprinting.

That said, I couldn't find anything related to that behavior when I tried to look it up. Hopefully this question can help others curious about this behavior.
