Site Favicon and New episode pill not showing

[resuta566]

Describe the Bug

New Episode and site favicon are working but on FF it works sometimes?

FF network tab

FF Console

Steps to reproduce the behavior

I don't know how to reproduce this behavior from FF because seems to be a server-side certificate issue at least based on when I searched for the error text, at least for the favicon.

Browser

Firefox 129
