I'm experiencing a problem with both Firefox and SeaMonkey opening online pdf documents. (Note the attached screenshot.) file:///home/al/iexplore-mozilla/MHDataXfer.pdf-page.png

As we can see, the page is blank. If I copy the page to a folder on my computer, I can then open the invisible pdf file using Adobe Reader 9, and it is perfectly readable and can be printed.

If I use Internet Explorer 6, I can navigate to the same page, and open the same pdf file online, and it is perfectly readable online in an Adobe pdf format, and can be printed directly from that page.
I've been dinking around with this problem for some time. Although I can use the work-around mentioned, saving the page to my computer, and opening it separately with Adobe, this is really annoying.
This does not happen on all sites. In fact, on most sites Adobe reader works just fine. The maintainer of the site, not surprisingly, suggests that I use Internet Explorer, as that is the browser which they support.

Any clues?
Thanks, owa:confused:

Do you have a special reason to use Adobe PDF reader instead of an open source alternative?

Even when I was a clueless Windows user I didn't use it. It sucks really bad. Have you tried Evince (apt:evince)? I use Okular (I'm on KDE) and it works great, although for on-line viewing I have solved all my problems with gPDF (https://addons.mozilla.org/en-US/firefox/addon/14814). It scan webpages for pdf links and set them to open with Google PDF viewer. Works like a charm.
