Problem with PDF in Firefox in OpenSUSE
 

I've had this issue since OpenSUSE 10.5 and Firefox 2.x. Now I'm on OpenSUSE 11.2 and Firefox 3.5.6. Here's the issue: I log into various sites to get my bank statements, utility bills, etc. They are all in PDF, and they open up acrobat reader and from there I save the bill as a permanent record. The first one I open opens fine. Subsequent sessions with subsequent providers (banks, whatever) opens up a new window as if to show me the PDF, but no PDF is there. Status on the window shows "done." No error messages. I have to shut firefox down, restart, log in again, and then it downloads fine. It's getting annoying.

Thanks in advance for any and all ideas.

Two questions...

Does it happen only when you download PDF from sites that have encryption?

Does the same thing happen if you use the KDE viewer Okular?

When it happens
 

All the sites I care about where this happens are using encryption. And to clarify: the problem happens when firfox is managing the file stream for me -- not when it offers to let me download it -- but when it opens a new window or a new tab and attempts to display the pdf file for me. I never explicitly configured this. Something set it up for me, and I became a user at that point. And I suppose that since I installed acrobat reader, then it decided it should use that software.
