Uppon closer inspection the window does not turn completely black, but rather extremely dark.
Comment 2 fanzhuyifan 2023-11-21 00:12:17 UTC 
I just realized that this happens for all windows placed on the external monitor (they turn extremely dark), and has nothing to do with firefox.
This is a regression in plasma 6.
Comment 3 fanzhuyifan 2023-11-21 05:11:31 UTC 
Yet another update: when I reported the problem, I was using a hybrid graphics system (nvidia dGPU and intel iGPU) with dynamic switching (optimus). I tried disabling my iGPU and I discovered that the problem occurs on both screens, instead of just on the external monitar. So this is probably a problem related to nvidia.
