How to workaround login form not loading due to "Load denied by X-Frame-Options" ?

Login form which I access on page https://portal.librus.pl/rodzina/synergia/loguj loads correctly on Firefox Quantum 68.2.0esr (64-bit) but fails to show up on Firefox Nightly 72.0a1 (2019-11-04) (64-bit). I see "form is loading" message (in Polish language) with following error on the js console:

Load denied by X-Frame-Options: “deny” from “https://synergia.librus.pl/loguj/portalRodzina?v=1572944172”, site does not permit any framing. Attempted to load into “https://portal.librus.pl/rodzina/synergia/loguj”.

This happens also after disabling all addons. I also tried with user forum suggestion to disable dom.storage.next_gen in about: config, but it still does not load. Expected behavior: login form loads correctly.

Please advise if this is Firefox issue or rather application issue, i.e. improper use of the X-Frame-Options. Thank you, Kamila Chyla

Hi Kamila.

You're right, it's an application issue, see

and I don't know any workaround for it. I think that you should inform them about it on pomoc@librus.pl .

Thank you. I contacted the support at librus.pl - the support team suggested to clean the cookies in my browser, which actually "helped". This of course does not solve application issue but is a kind of workaround...
