There are many variations on this issue. E.g. I'm trying to read up on the Semitic sun god (don't ask), for which I found a pay-walled jstor pdf: https://www.jstor.org/stable/pdf/23502986.pdf

Now there are several options:

• Does work: open link in this tab. Shows login page.
• Does work: enter "?" + URL in the address bar, click on first/only google result. (Variant on the above; easiest way to create a link if you just have the -pdf URL.)
• Does not work: copy and paste URL in a new tab. "Invalid or corrupted PDF file."
• Does not work: open link in new tab. Also "Invalid or corrupted PDF file."
• Does not work: open link properly with one of the first methods above; close and reopen brave. "Invalid or corrupted PDF file." or even "Your file was not found".

This is especially annoying when searching and your search result contains a pdf link. Then you should open all the other interesting (normal html) results in new tabs, then left-click on the pdf link. And it is even more annoying if you have two or more pdf results, because you have to perform the search another time in a new tab.

I'm sooo happy I found the workaround in the second bullet above. Because I often open many tabs from a Google result, continue searching with different keywords, opening more tabs, etc. Then I go read the tabs, and they are broken pdfs. But by then the original search is long gone, so there is no link to 'left-click' on. Now I just prefix a "?" to the URL and click on the result.

@BrendanEich ran into the same issue mentioned in #14674 (comment) when attempting to load the following link:

https://github.com/Microsoft/MSRC-Security-Research/blob/master/presentations/2018_02_OffensiveCon/The%20Evolution%20of%20CFI%20Attacks%20and%20Defenses.pdf

It looks like browser-laptop is having issues loading URL's that are ending in .pdf but are actually websites that have PDF's embedded. In the example @hugobuddel mentioned above, loading https://www.jstor.org/stable/pdf/23502986.pdf will redirect the user to https://www.jstor.org/stable/pdf/23502986.pdf?seq=1#page_scan_tab_contents which appears to be a website with an embedded PDF.

Loading the data URL's directly in browser-laptop works without any problems, example:

• https://raw.githubusercontent.com/Microsoft/MSRC-Security-Research/ed3b80279004c344c3aa559677984a7b7f350663/presentations/2018_02_OffensiveCon/The%20Evolution%20of%20CFI%20Attacks%20and%20Defenses.pdf
• https://github.com//tinkertim/StackCOC/raw/master/The%20Stack%20Exchange%20Network%20Code%20of%20Conduct%20(R7).pdf

All of the examples within this issue are loading correctly within brave-core so it defniitely seems like it's related to muon.

Thanks @tbates

I've added your example to what seems like the corresponding brave-browser issue: brave/brave-browser#1033

Also a problem with eBay shipping label pop-up and/or "Reprint" label
(works in Chrome every time)

Get the same "Invalid or Corrupt PDF file" message (in the red bar across the top)
Clicking "More Info" = PDF.js v2.0.673 (build: 31012570) - Message: Invalid PDF structure

[oxfordia]

Just got another one while trying to "view" my Chase online statement:

"Unexpected Server Response"
PDF.js v2.0.673 (build: 31012570)
Message: Unexpected server response (401) while retrieving PDF
"https://secure.07a.chase.com/svc/......chase.com"

SAME "PDF.js v2.0.673 (build: 31012570)"

@oxfordia do you by any chance have the new Brave installed? You can download the latest versions from the following links:

• https://brave.com/download [release channel]
• https://brave.com/download-beta [beta channel]
• https://brave.com/download-dev [dev channel]

Explanation regarding the difference between the above channels:

https://support.brave.com/hc/en-us/articles/360017916752-What-is-the-difference-between-Beta-Dev-and-Release-builds-

If you do download one of the above versions, could you run through the issues that you mentioned above and see if they're still reproducible? If they are, can you please update brave/brave-browser#1033 with more information? Much appreciated!
