Browser-laptop: PDF.js viewer error

[luixxiul]

Description

https://community.brave.com/t/pdf-js-viewer-error/7825?u=suguru

I’ve noticed a glitch when trying to open download links via email (Airmail 3). Scenario… I’ve sent dropbox links to a client to download some PDF files. Sent message links open up a brave window and fail to download. I get an ‘Invalid or corrupt PDF file’ message when the PDF.js viewer file loads. Only happens in Brave (0.18.36), links work fine in Safari (10.1.2). Macbook Pro running OS 10.10.5. I don’t think the client (Windows) had an issue either but this is a recurring issue with Brave. Interrupts my workflow a bit. Hoping somebody can shed some light on it.

Steps to Reproduce

1. Send dropbox links to a client to download some PDF files.
2. Send message links open up a brave window and fail to download

Actual result:

The user claims he got an ‘Invalid or corrupt PDF file’ message when the PDF.js viewer file loaded.

Expected result:

It should load the PDF file.

It seems to happen when the url is not pointing to a pdf itself, but working as a router or container for the file itself.
The same issue happens when trying to open a pdf link on github, i.e: https://github.com/datproject/docs/blob/master/papers/dat-paper.pdf

This happens a lot.

Please correct the original post's Actual Result where it says "corrupt". It should say "corrupted". This is not a nit. People searching for the error message need this correctly quoted in the bug report.
