I really like this extension but now I was trying to use it and I get three grey dots and it's not working. I saw more people is having the same issue, so I hope it will be fixed soon.
UPD: The new version 11.1.13 is available on Firefox. -- Yes, it happened to me too. It is a youtube update https://theverge.com/2022/4/12/23022541/youtube-sidebar-outage-settings-account-switch-sign-in I've prepared a quick fix on the extension side. It'll be available after approving the new version soon. I'll notify you.
