Is it possible completely block feedburner refferals?

This review is for a previous version of the add-on (1.0). 

Yes, by using 2.0 you can completely block Feedburner referrals - or any kind of tracking/referral tags indeed.

The new 2.0 version is waiting for review as of time of this write, so download it from the versions history page if you can't wait.
