I get a partially transparent checkerboard pattern when I open some pdf documents in the Firefox browser..
If the document is saved and reopened with a pdf reader, pattern is absent. How can I get rid of this annoyance ?

Which viewer do you use to display the PDF file in Firefox?
Is that the PDF viewer extension (https://addons.mozilla.org/firefox/ad.../pdfjs/) or the Abode Reader plugin or another extension?
Try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

Thank you very much, but I am not sure how I find out what viewer is currently being used by Firefox.
Your system details list shows a "Adobe PDF Plug-In For Firefox and Netscape 10.1.4" plugin, so that is the one that is probably used.

Thank you Cor-el. 1. I did change to the Adobe PDF Plug in for Firefox and selected it. 2. I also did disable the hardware acceleration by unchecking. 3. Completely logged out of all Firefox windows, but unfortunately, the very fine checkerboard screening mask persists. Best regards, JJaldan
