I’ve installed official “Facebook Integration” plugin from Shopware Labs in GIT, it’s working fine in Google Chrome but it is not visible in Mozilla Firefox. Please check the image below for the issue in firebug.
Thank you for the reply, but I need Share and Like button in product detail page, the link which you have provided Shares the complete page which is not my requirement.
I hope you got my quer, will be waiting for next reply.
