URL of experiment: FSs [PsychoPy]
Description of the problem:
Several pre-existing on-going live running online experiments hosted on Pavlovia that were working last year are now broken (example above).
The reason appears to be the introduction of a new HTTP header on run.pavlovia.org:

Firefox Can’t Open This Page
To protect your security, run.pavlovia.org will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

This is affecting on-going experiments that we are collecting weekly data in (except for the school break ending tomorrow). If there is any way to roll-back the change or set
X-Frame-Options: SAMEORIGIN, that would be much appreciated, otherwise these experiments are basically ruined.
