Facebook and blocked frame errors

Hi,
I’m new to WP and I recently created my first blog. I managed to publish it and do most of the things I was imaging but now I’m trying to fix all the small errors appearing in the JS console.

In particular I get all this errors about social plugins:

##########################
#  The endpoint used to load this resource has been deprecated.
#  Please update to the current Facebook JavaScript SDK.
#  https://developers.facebook.com/docs/reference/javascript/
########################## FB.Share:55
i FB.Share:55

FB.init has already been called - this could indicate a problem

Blocked a frame with origin "http://static.ak.facebook.com" from accessing a frame with origin "http://www.blogcielomareterra.it". The frame requesting access set "document.domain" to "facebook.com", but the frame being accessed did not. Both must set "document.domain" to the same value to allow access.

Resource interpreted as Script but transferred with MIME type text/plain: "http://widgets.pinterest.com/v3/pidgets/log/?via=http%3A%2F%2Fwww.blogcielo…terra.it%2F%3Fp%3D123&type=pidget&callback=PIN_1372953506944.f.callback[1]]".
n.(anonymous function).f.call
n.(anonymous function).f.log
(anonymous function)

The strange things is that it’s not always the same. Sometimes it shows just a few errors about MIME type or else. You can have a look at it here http://www.blogcielomareterra.it/?p=123 but I suggest several refresh with the js console open to see what happens.

How can I solve all this or at least part of it? Where should I start?

Thanks in advance
