Reproducible: Always Steps to Reproduce: 1. open a few (5) different URLs in disjoint tabs. 2. "Save and Quit" 3. restart firefox Actual Results: Some of the tabs have addressbars which do not show a favicon or site icon nor a placeholder icon. The "missing icon" is not draggable (i.e. in Order to bookmark). Expected Results: Display favicons/site icons/placeholders as right before the session was saved.
