1720411 - Incorrect rendering in Firefox PDF viewer

Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect, P1)

Description

Attachment: pdf_checkbox_issue.png

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Recent update to Firefox v.90 (as well as in FF dev. edition v.91) caused an issue to show all check boxes are CHECKED by default in built-in FF PDF viewer.

Actual results:

The PDF doc was generated programmatically on webserver side based on a blank PDF doc with acrofields (template). The result is absolutely all check boxes and radio buttons are checked by default giving a corrupted output, supposedly a built-in pdf.js is changed as well.

Expected results:

Normally those check boxes should be unmarked (non-checked). Such issue never happened in earlier versions of FF. The built-in PDF output is normal in Google Chrome and MS Edge browsers. Please see screenshots in attachment.

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Could you try using mozregression to figure out exactly when this was introduced?

And could you attach the PDF?

I'm not familiar with mozregression but will try it, also attached the PDF "test.pdf", all check boxes are checked in FF v.90/91, looks normal in Google Chrome and Acrobat Reader.

Thanks for the fix, I noticed the issue is PARTIALLY resolved in FF dev. edition v91.0b6. The similar problem still exists in another PDF template with checkbox fields, please see attached file test1.pdf. The doc is correctly shown in Google Chrome and Acrobat Reader, in FF all checkboxes are UNCHECKED.

Please file a new bug for each document, since it's very unlikely that the document in https://bugzilla.mozilla.org/show_bug.cgi?id=1720411#c8 suffers from the same problem as the one fixed here. Having multiple distinct problems reported in the same bug unfortunately makes tracking things more difficult overall.
