The photon UI under photon.lemmy.world does not work for me in Firefox 122 under Linux, showing nothing but blank page when I open it. It works in Chromium and in Firefox on Android.
When I open the developer console, I get the following error message:
Uncaught (in promise) TypeError: e.moderation is undefined
Anyway, I disabled all of those in Firefox’ Add-On page (so not just via their own disable buttons), reloaded the page and… no difference. Still just a blank page.
Try opening on a new profile. Maybe some about:config setting is causing the error
