Firefox 3 (exactly beta 4, haven't tested other versions) does not allow the toolbar to be installed because "it does not offer secure updates". This error message pops up once the download of the xpi is finished and removes it automatically without installing it at all - the user has no choice to install it anyway.
Firefox 3 and LOKI still do not work together!! Eye-Fi Explorer works fine in my Nikon D50. I also need to take notes on my urban explorations on my 12 inch WinXP notebook where LOKI is still a dead duck with fully released Firefox 3. one usage flies like an eagle but other is a dead duck. The game is in play lets stop playing catch up and get this fixed - this is the combination I have been anxiously awaiting to make my photography habit fun and easy as well as letting folks know where I am working today - killer fun. Any release date on the fix!
