Privdog prevents posting YT comments in FF

When you install privdog it enables firefox’s deny on 3rd party cookies. Because of this, you won’t be able to post comments on Youtube. Even if you disable privdog it won’t work because privdog has enabled the option in the firefox’s settings. The only solution is to disable the blocking of 3rd party cookies. Can you guys fix this? Why does privdog have to block 3rd party cookies by default in Firefox anyways?
I think this is caused by Google linking Google+ and Youtube comments.

Same problem.
I do not use too many other functions on other websites, even though I removed the extension I always blocking, plus the extension back after a reboot
