Clicking like button asks for confirmation

Hello

I wonder why suddenly clicking on FaceBook like button asks for confirmation?
On other websites it doesn't ask for confirmation
Try here: www.sportskazvijezda.club/skola-skijanja-sljeme.html
When clicking like button on the bottom, it changes like button into confirm, and after clicking it it pops up a window where I need to click confirm again.
Previously only one click was needed to like something.
Is this JFBC behavior or facebook changed something?
I would like have it working as single click like, like before.

Latest Joomla and JFBC.

Thanks,
Regards
