I can confirm that this is exactly how the problem affects me, too.

It is only restricted to a single window, so no need to restart firefox (for those of us who spread multiple windows around on different desktops :). Closing it and opening a new one resolves it. It happens rarely, but not rarely enough to be able to forget about it. It occurs on all Ubuntu 8.10 installations I have, and it has been a problem (albeit small) for a long time. I do not think it is related to Delicious, as I've also experienced the problem with a clean browser profile (IIRC) and I always update to latest version of Delicious (now at v2.1.018).
