In my case I upgraded to Lucid a couple of weeks ago and firefox worked fine until today. I had made no changes to my firefox set up recently. I use a few different firefox profiles and all the ones I tested were affected, and they all work fine following the removal of libmoon et al. The simplest profile I tested has only the Adblock Plus add on installed and is otherwise a pretty standard set up.
