Did you search for similar issues before submitting this one?

Yes.

Describe the issue you encountered:

A PDF (DM'ed over Slack to @diracdeltas because confidential until reduced results in the "PDF is invalid or corrupted" error in Brave, but works in Firefox with its PDF.js, and works in Chrome.

(Sorry, short on time -- I didn't test in Chrome with the PDF.js extension yet.)

Expected behavior:

The PDF renders properly.

• Platform (Win7, 8, 10? macOS? Linux distro?): macOS El Capitan.
• Brave Version: 0.11.1
• Steps to reproduce:
  1. Load (private, for now) PDF via file: URL.
  2. Get error.
  3. Confirm works in Firefox loaded same way.

Also broken in Chrome w/ pdfjs extension. @Rob--W do you have debugging tips? chrome console error:

[Rob--W]

Looks like the file is malformed, and/or not correctly parsed by PDF.js. I'd start with building the latest version of PDF.js from master, and if that doesn't resolve the issue, check which Firefox/PDF.js version was used.

If you (with the reporter's consent) share the PDF file by mail, then I can also take a look if needed.

same error in Chrome with pdfjs built from master (10f9f11ec4cb1221c8be5335f1bf5aed19c558c0). @BrendanEich could you generate a PDF using the same process as the broken one but without the confidential information?

[bbondy]

The PDF is our hiring document, I just generated a new one with fake info. It is not a public document though even know it is fake info so I will email you @Rob--W. Thanks for taking a look.
