Does it work in the firefox safemode ?

Please post the graphic section from about:support if the safemode makes it working

Disabling the hardware acceleration in tools/options/advanced/general followed by a Firefox restart should fix this.

There is a button for that on top of about:support, use it to copy and remove the parts you don't need to publish.

Are your GPU drivers up-to-date? If not, could you update, please.

I have upgraded the driver. Not much changed, the window is now whole black. It is not always reproducible, just from time to time, and goes back to normal after mouse click.
