Redirect to currentpage after login


I’m currently using Ultimate Facebook to let users login with their facebook accounts. I only use Facebook login on this site.

When users are not logged in, I do not display the content instead I display facebook login with wordpress standard wp_login_form() within my theme.

After users login I want them to stay on the same page instead of getting redirected to WP-admin or any other page. (just reloading the page so they can view content)

Also can I change the default text of “login to facebook” without using shortcode?
