Games boxes don't appear in non-private Window in Firefox

[ericzolf]

If I go to arcade.redhat.com, even with NoScript disabled (or at least redhat.com and unpkg.com allowed) and with all cookies removed, the page shows without the game "boxes" (see screenshot below). With exactly the same setup, a private window shows me the boxes. That doesn't really make sense to me, I have no clue what explains the difference in behaviour.

If I block unpkg.com in NoScript, then the behaviour is the same in both types of Windows.

@ericzolf Could you give it another try and see if you still have the same issue? I had the same problem, and traced it to a browser extension that included a CSS animation with the same name as the animation I'm using to slide in the cards. I updated the arcade site and submitted a PR to the extension, so if you're seeing that same issue, it should be resolved now.
