PDF Viewer

Doesn't work for all PDFs, such as those that require lengthy downloading via complex mechanisms, including those at Hathitrust. However, it otherwise works superbly, and unlike the new default in the Chrome PDF viewer, it does not perform optical character recognition unasked, or at all. When you download PDFs for archival and research purposes, you don't want arbitrary OCR being done on files, and this plugin does not do that, which is great.

Was amazing, now I can only open old downloads, anytime I try to see new files it just shows me a blank screen where I can't do anything and the icon is gray.
