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.

A little room for improvement Rated 4 out of 5 stars

I would say that it is a great start for the add-on, but there is plenty of room for improvement. For starters, the name and icon are a bit confusing. F1 associates with help, not sharing. The icon is pretty basic- it could use a re-think. In fact, I think the best solution is to get rid of the icon and add the feature into the Website ID like it is in Firefox Mobile. Also, although the included services are good enough for me, I could see why others would want more options.

This review is for a previous version of the add-on (0.8.2).
