I am unable to livestream video services from a monastery in the UK. I have clicked into the little shield at the left end of the web address bar in order to turn off the enhanced protection, but this does not have any effect, even though the website shows up as having had the protection disabled. I don't know whether I need to do anything in Firefox settings.

I was advised to use Google Chrome, and that browser does let me enter, but I prefer to stay with Firefox for all my browsing. I am an elderly person, and have to work harder than my children and grandchildren to keep up-to-date. If you could help me with some very clear instructions with the minumum of technical jargon I would be most grateful. I submit below a screenshot of what I see on the site despite the protection having been switched off on the little shield.
