If you add the following to your template's CSS file, it will make the comment box use 100% width of the containing area, which is good for responsive templates:
#fbcomments, .fb_iframe_widget, .fb_iframe_widget[style], .fb_iframe_widget iframe[style], #fbcomments iframe[style], .fb_iframe_widget span { width: 100% !important; }
This change will be included in the next release of JFBConnect as well.
Hope that helps,
Alex
