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
Same, works for me on Firefox 121. @OP maybe check if there’s an extension interfering with it.
