I have installed and configured JFBConnect, integrating it with joomsocial, the first thing is that I want to know how I do so that the bar that appears when I authenticate with Facebook in the lower part of the site, does not appear (See image).
That bar is shown by default to administrators of the site, not regular users. You can 1) disable the toolbar with JFBConnect backend > Configuration > General area > 'Enable Social Toolbar' setting and 2) change the permissions of which users get to see it by changing the user group permissions (JFBConnect backend > Overview > Options button)
The second is about the integration with joosocial and the site, when I write a comment on joomsocial appears on Facebook, well, that's what I'm looking for, but when I share a link, in joomsocial the perfect opengraph is displayed, but on Facebook only appears the link (Look at image)
When you share a link, Facebook uses the Open Graph tags on the page to generate that preview of the site with the image, link and description of the page. Facebook used to provide the ability for comments posted on your site to be also pushed onto your Facebook page. However, they have recently removed Comment Mirroring functionality and I don't know of any way to do what you're asking for now.
I hope this helps explain, but let us know if you have further questions.
