Youtubelinks are blocked if you're logged in.

I tried to reproduce the issue when...

[X] AdNauseam is the only extension.
[X] AdNauseam uses default lists and settings.
[X] using a new, unmodified browser profile.

Description

When clicking on a youtube-link for example a link i found via some search-engine (not using google here) The Website doesn't load at all. Same is also happening with Youtube-Tabs when Firefox is set to Show my windows and tabs from last time . After restarting the Youtube Tabs will look like on my image.

It is somehow related with being logged in on Youtube. If you aren't logged in it will work just fine. Clearing cookies didn't help - as soon as i'm logged in the Issue will appear again.

It's happening with all (other) Plugins disabled, new Profile and in Private-Mode as well.
