i have been using fd since its release on my mac. now on ff3. since fd 2.1, i am having the following problem:

for certain sites (deviantart,ilounge,macworld), i get thumbnails that belong to pages that have not completely finished loading. certain images on the page dont show up, instead i see placeholders.

i suspected certain other addons such as adblock and cooliris were interfereing, and i tried to disable and uninstall them. i deleted old thumbnails from fastdial folder and allowed all images to be generated from the start. i tried java scaling, etc. nothing seems to be useful. can you please help?
