Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect, P4)

Description

[Ralf Hauser]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0
Build ID: 20130307023931

Steps to reproduce:

downloaded a pdf and viewed it inline with Firefox PDF viewer, pdf.js 


Actual results:

a digital signature was on the pdf, but firefox presented it as if it were unsigned


Expected results:

it should have indicated that the document is signed, better even with some statement about the validity of the signature.
For comparison: The signature is nicely shown with MSIE

Until the signature is fully implemented with PDFjs, instead of hiding the signature Firefox should show some advertisement saying that is hiden and it should be opened with an external PDF reader to see it. In our company we must disable pdfjs totally to avoid problems.

Same problem here with FF 82.0.2 (64) and Windows10.
Handwritten signature in PDF is not displayed in FF.
With Adobe, Foxit, GoogleChrome and Edge it's working.

Are pdfjs bugs tracked here or on Github? https://github.com/mozilla/pdf.js/issues/1076 , "Digital signatures in pdf.js", seems to be the same bug, with much more detail.

Thanks to PR: https://github.com/mozilla/pdf.js/pull/13214 signatures in PDF will be displayed but they won't be validated.
So display a banner to warn user about that.
