Comment (by pospeselr):
Better patch following suggestions from Arthur, now using the secret
chrome-only SetOriginAttributes function:
https://gitweb.torproject.org/user/richard/tor-
browser.git/commit/?h=bug_26540_v4
The origin attributes are set immediately after channel creation, FPI
regarding cookies is now enforced correctly, and pdfjs's range-based
requests now go out on the correct channel (the channel for the hosted
pdf's domain if entered directly in the title bar, and the first party
domain's when embedded via an iframe or embed node).
Verified on jsbin.com with the following html:
{{{
<!DOCTYPE html>
<html>
<body>
<iframe
src="http://cadwe.free.fr/cadr/DD4/Player%27s%20Handbook.pdf";></iframe>
</body>
</html>
}}}
