Thanks Antonio, that demonstrates the problem very clearly.
If you didn't change the default options, you should be in an X11 session. Just to make sure, can you please share the output of running the following command in a terminal?
echo $XDG_SESSION_TYPE
Also, it would be useful if you could test another browser (e.g. chromium) and let us know whether you can observe the same problem with it.
