I develop wordpress websites on FF Dev Ed on a Mac running macOS12.7.4. This current problem is one I've never seen before. * In a regular window of FFDE, dropdown items on the menu, don't drop down. * A youtube video, visible in the source and in the editor, doesn't display on the page. * A gallery of logos doesn't appear on the page, though it does in the editor and the editor's preview. These problems DON'T APPEAR * in a private window, * in vanilla Firefox, * in another user account, using FFDE * on other websites, using FFDE * in other browsers, * on other computers, using FFDE In all those cases, site works perfectly. Actions: * refreshed the page (dozens of times), * cleared the site cache, the browser cache (Managed the data AND cleared the data) * turned off all extensions, * put the browser in troubleshooting mode, all with no change. Although I don't think anyone else will see the problem, the site is https://homeopathyschool.org What am I missing?
