Not sure what the problem is, but it is working now in Firefox if I copy the URL into a new tab or window (it wasn't yesterday; didn't check that the day before), but sill displays the thumbnail when left or right clicking on the link.
BTW this is on my old computer, so it doesn't need to be updated. I may find uses for it even after I've transferred everything over to my new computer, but but keeping up with the latest updates is not going to be one of them (duel booting Win98/XP, DD/BD era hardware).
