(3) The thumbnails are empty, and in the browser console: Blocked https://web.archive.org/web/20180211235741if_/https://research.torproject.org/techreports/tbb-forensic-analysis-2013-06-28.pdf in page https://web.archive.org/web/20180211235741/https://research.torproject.org/techreports/tbb-forensic-analysis-2013-06-28.pdf from extracting canvas data. re[/pdf.js/web/viewer.js:3311.](/pdf.js/web/viewer.js:3311.`)

Note that it's the local re[/pdf.js/web/viewer.js](/pdf.js/web/viewer.js`) that is invoked and not some bundled pdf.js.

To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
