It might have something to do with a new feature called WebRender. Take a look at this thread: UI glitch: black box in the top-left corner

Start Firefox in Safe Mode {web link}

Thank you, that's it! After setting gfx.webrender.enabled to true and restarting the browser there is no black rectangle anymore!
