Screenshot of the broken Firefox window

Firefox is interfering with KWin after an update in openSUSE Tumbleweed roughly a few hours ago. All other applications (including Thunderbird) work fine, but when I startup Firefox its window has no borders whereas the titlebar appears gray. The window can also not be resized, it can only be minimized / restored by dragging it from and to the screen edges.

I'm attaching a screenshot of the broken FF window. The gray titlebar is NOT the theme I'm currently using (Aurorae), and I have no idea what skin the buttons to its upper-right are from either. KWin should not be allowing applications to have custom window managers, this might be an issue with some fundamental library.

Firefox started to use client side decoration. This decoration is not done by KWin, it's Firefox. Please report to Mozilla.
