So I am using the AddThiss share toolbar and followed the configurations correctly. Upon checking in storefront, The facebook and Twitter share is stuck in loading (Contacting Facebook... and Contacting Twitter...). I checked the other sites I am working on and this is also happening. I checked the addthis demo and confirmed that it is happening there as well. Is there a fix for this?
Configured and expected the FB and twitter share to work properly.
We had the same issue. AddThis is shutting down as you can see on their homepage.

AddToAny is probably the best alternative, and I see they already have a blog post and a guide for switching to AddToAny from AddThis.
