I've read a number of the posts on this problem and the solutions suggest that the security settings are the cause of the problem.

I can't even open a .PDF file in an email when using FF. However, I have no problems doing this when I use IE.

I've tried resetting FF but this achieves nothing.

Has FF released any fix for this ?
