What's with the Facebook pop-up when I hit the submit button (when answering a question)?

This is REALLY annoying and merely serves to add to my hatred of Facebook and that punk, Zuckerburg.

Is this going to be permanent on Answers? And, most of all: how can I get RID OF IT??!!

Thanks!
Update: ..
Oh! AND it happens when I ask a question. AUG!!!!
Update 2: Aha! Thanks to those who have the solution! Would've been nice if Yahoo had given us a heads-up...
