Rated 3 out of 5 stars
Add-on not working - popup is a web hosting site. The quoted home page & support site make no mention of this add-on.If it had been possible I would have given this ZERO STARS.
Tried again today following developers reply - it is working now. So have upped my rating. The main difficulty I have now is being able to 'like' photos in a particular users feed - is it possible?
This was just a temporary web hosting problem on that particular day....
