A cypherpunk there suggested that this was a NoScript bug.Steps to reproduce the issue:There's nothing in the stuff that is disabled at Medium security setting that would cause the PDF to not show up, so this is most definitely a bug.
- Open Stock Tor Browser 7.5a4.
- Set the security setting to Low.
- Visit https://web.archive.org/save/https://sv ... design.pdf, after some time PDF should show up.
- Set the security setting to Medium.
- Refresh the page.
- PDF wont show up no matter how much you wait
