Site loads and reloads, Facebook like button dissapears

This happens on my mobile site www.m.straumfors.com
Anyone know why this happens?
(I’ve had some trouble getting the like button to show at all)

It works fine with my iphone safari.
What is your browser?

Wow, that sounds strange. Im running safari on iphone 6, and safari 10.10.3 on my mac.
the facebook like button seem to just dissapear :-/

Anyways, this site seems to be a bit heavy.
Putting Loading indicator or making images light should make it better.
