There were a couple of style releated bugs that we found that have just been fixed. Both related to the IE browser and not Firefox.
The first issue is that when images are posted beyond a certain width they cause the LH menu to disappear to the bottom, the problem was that the background colour for quoted text was being displayed over inset images making it look like only half of them had loaded (CSS styling issue).
Both issues have been addressed, so things should look better in IE browsers now.
