Test Screen Name Mar 2, 2013 3:28 AM (in response to shimax)Adobe don't own the PDF standard any more. It is now managed by ISO. Adobe could disapprove all they want, but I don't see it could help.

2. Re: Firefox's pdf.js completely ignores PDF document permissions.
Dave Merchant Mar 2, 2013 5:55 AM (in response to shimax)This isn't a new issue - most of the third-party PDF reading applications have been ignoring the permissions headers in a PDF for years, and some claim it's perfectly valid for a user to be able to override password-based restrictions on copying/printing under 'fair use'. Adobe disagrees, as do I, but the nature of the PDF document structure means that it's trivial for any application to ignore those restrictions. You certainly don't need the password. Acrobat warns you the first time you use the Protection tools that Adobe always respects the permissions you set even if other vendors choose not to.
As has been said many times; the only way to truly secure the content of a PDF file against printing or copying is to use LiveCycle digital rights management, as that forces the PDF to be opened in Adobe software and nothing else. If you cannot afford LCDRM, you have to accept that your 'secured' PDFs are anything but.

This is right. But the impact was much smaller. Literally millions of people use Firefox in the whole world. The impact was too big.

pwillener Mar 2, 2013 8:18 PM (in response to shimax)Millions of people will also try to get away from PDF.js as soon as possible, as its document display capabilities are ridiculous. See http://forums.adobe.com/thread/1158136
