Iceweasel's "Awesom bar" history is missing icons for some websites since upgrade from v7 to v8. For the explanation of this bug I use the terms of http://www.mozilla.org/en-US/firefox/central/ . For example the icon of http://www.dict.cc/ isn't shown by the "Awesom bar" history. But the "Fav"icon still is displayed for the "Instand Website ID" button and for tabs. - Ralf
