PDF open doesn't seem to work in Opera or Firefox

I tried to open a PDF, and I tried clicking on "print", but neither worked in Firefox. So I tried Opera - also didn't work. Then I tried IE - that one reqarded my click with an offer to become a member to download the file.

You must be logged in with your I'bles username in order to access the PDF (as I just confirmed). With the little popup, just enter your existing username and password and the PDF will follow.

Do you have your Opera and Firefox browers configured to not automatically open downloads. Such a configuration is considered more secure. Check your Desktop, or Downloads directory/folder, and see if a PDF file has appeared there.
