Great concept... getting there. Rated 4 out of 5 stars
I am not sure in detail how this works, but there is a delay in the bubble that is likely related to my slow internet. I think that the name and icon need to change (kinda misleading). I would also like to see, as I had said at some earlier point, for this to be moved into the favicon as seen in firefox mobile. It would also be great to see private messages available in facebook. Otherwise, great.This user has a previous review of this add-on.
