Affected platforms

• Windows 10, macOS 11.0

Steps to reproduce
pdfjs.renderInteractiveForms - enabled

1. Launch Firefox;
2. Access a PDF form with fillable content;
3. Right Click in any text-input field or dropdown menu;

Expected result

• expected options are displayed;

Actual result

• login - user account data should not be available to pre-fill in such forms;

Additional notes:

• S2/3 as suggested severity due to the potential data secure issues might be caused by users that wouldn't pay attention;
• attached screenshot with the issue;

The screenshot appears to be missing, but from what I can find this is a browser setting and can't be disabled programmatically. If that is indeed true and we want this, this requires an upstream issue in Bugzilla as well since that would require a Firefox change.

Uploaded the image as well.

@brendandahl Do you know if this can be disabled programmatically? I couldn't find any resources for that, so I think this is an upstream issue instead?

[brendandahl]

I think this will have to be fixed upstream.

I've created an upstream bug for this:

Patch verified. Closing issue.
