I have encountered software incompatibility that causing the latest versions of FxiF 0.4.X not working with the later versions of the Firefox 3.6.X or XX, with two machines out of three had a crashing problem so that no EXIF data could be displayed.
So, I tried installing the 0.3.X of the FxIF instead, it works like a charm! One of which can be downloaded or simply directly installed here:-

Btw, the older FxIF versions 0.2.X are completely incompatible with Firefox 3.6 and installation is not allowed to proceed.
If you are also countering the same problem, try using the FxIF 0.3 XPI above. Good luck!
