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
Firefox 122 (Flatpak) on Mint 21.3 Cinnamon and it’s working fine for me.
Turn off all your extensions and turn them back on one by one to see if that’s the cause.
Though I must say I stopped using Photon because it was broken for well over a month for me to the point of it being unusable.
What was broken about it?
There was an error saying it couldn’t read/find my profile and just wouldn’t load.
There’s really not much there. There is uBlock Origin (already deactivated in the screenshot), HTTPS Everywhere (all that does is redirect http websites to their https equivalent, but this was already using https anyway), Greasemonkey (Not configured to do anything on this URL) and finally RES (doesn’t have permissions to do anything outside of reddit)…
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
