Hi all Not sure if anyone can help I have been using firefox for a while but have come up against a problem viewing Djvu images on one family history site It triggers a suggestion to download a plug in but no plug in can be found, automatically or manually, does anyone know if one is available anywhere? I have looked at findmypast who also use Djvu and have downloaded the plug in and installed it but it does not seem to work with the other site Any ideas? It works quite happily under IE Nivard Ovington in Cornwall (UK)
