I am trying to open a .fdf file using safari and Mac OS 10.7.2. When I originally installed Adobe Reader I noticed that it said i needed MAC os 10.5.6 or some earlier version. When I try to open the .fdf file it flashes and displays a local address like users/user/downloads/filename.fdf until I have to force close safari. I have no idea what is going on any help is appreciated.
Why are you using Safari?
Do you have the original form (PDF) that the .fdf should populate?
Adobe Reader does not supoorts PDFViewer in Safari on OSX 10.7.x. Hence, please try to open the pdf/fdf in Adobe Reader instead of safari.
