Some letters are missing when I open a PDF in Firefox. Works fine in other browsers.
When I open a PDF using Firefox, some letters in words that are printed across the document are missing. I believe the creator of the document used a text box to add "Draft" on it. The D is missing. Other words I have found are "Copy Non-negotiable" and the C is missing. These same PDFs open fine in IE and Chrome. Have experienced it on V22-V25. Using Windows7

Are there embedded fonts used in the PDF file or the font that is set as default in Options > Content?
You can right-click the text and use "Inspect Element" to open the built-in Inspector and go to the Fonts tabs to see which font is used.

Starting in Firefox 19, PDF files will display by default in a built-in viewer. This viewer does not yet support all of the features of the Adobe viewer, and may also have some bugs. Other than changing viewers, as described in the following article, I'm not sure what to suggest.
The forum software detected your Firefox as version 12. Is that correct?
Version 12 is not secure; Mozilla discloses security flaws after each new release. Is something holding you back from upgrading to Firefox 25? Please let us know so we can suggest solutions or workarounds.
If Help > About Firefox shows Firefox 25.0.1, you may need to clear the preference that is misreporting your version number. See: How to reset the default user agent on Firefox.

jscher2000 - No, V12 is correct. That is the version I am using on my PC. Some of my customers are experiencing the issue and I am trying to find a solution to offer them in order to correct the issue. They are using versions ranging from V21 - V25. My company has chosen not to upgrade the version on our PCs at this time. For your suggestion to disable the built in viewer is already part of our process in assisting customers with opening our secured PDF files.
cor-el - I'm not sure how to answer your question. When we open the PDF the words "Copy Non-Negotiable" or "Draft" are showing across the middle of the page diagonally. Similar to a "Confidential" or "VOID" marking. The documents are loaded from our database to our website for the customer to view/print on their end.
Thank you both for your help
Is there a sample PDF online that illustrates this problem?
Unfortunately, no as it would show privileged details of our customer's document. :( I will have them verify they are doing the viewer steps you offered. If that does not work, then I'll come back. :) You have been very helpful and I appreciate your prompt responses!!
We're still seeing this issue (contrary to the bug being marked as fixed here: https://bugzilla.mozilla.org/show_bug.cgi?id=761539). Basically all the "1" characters aren't printing out. PDF file was created in InDesign.
Printed photo attached. PDF file: http://www.apca.com.au/docs/role-of-cheques---consultations/towards-the-digital-economy-milestones-report-%28april-2013%29.pdf - looks fine on screen using FF built-in PDF viewer (Win 7 64-bit, FFv26). Futura font looks to be mainly affected.
We regenerated the PDF in Acrobat and tested which fixed the problem (file sizes are much larger however).
