Firefox bookmarks favicons for dockers stuck on Unraid logo

[s449]

This is mildly Unraid related, but my Firefox favicons usually work, but every once in a while they seem to get reverted to just the Unraid logo. Currently they look like this:

Not sure why Radarr and Sonarr are okay.

 

All of these do have Favicons, so I'm not sure why they're not updating. I don't do any reverse proxy, so all of these point to: https://[local ip]:[port]

 

Anyone else with the same experience? How do you manage it?

Found a solution following the instructions in this answer: https://stackoverflow.com/a/46789939

 

However, I'm still anticipating they get reverted back. If they do, I'll try to report what might have caused it.
