You know, I have been noticing this for a long time. I use Mandriva
2006, which is ok, but that isn't it. Beginning with Mandrake-10.1, we
began using xorg rather than xfree, and I noticed that I can't read
pdf's online anymore.
I realize that you asked a Firefox question, and in fact I'm still using
Mozilla. I don't mean to seem out of order, but no one else answered.
What I have been doing for about a year is to save pdf's to my Documents
directory, and then opening them directly with Acrobat 7.
One thing that may be pertinent in my case is that I have been moving my
home directory over for several years, when I upgrade. I began my
present home under mandrake-9.0, and now I am using mandriva 2006.
I wonder if it matters. I do dread to start from scratch, but maybe
someone with a high-speed connection will volunteer.
