Redirectify

This extension intercepts requests to PDFs of papers on arXiv and some other sites (mainly machine learning publications) and redirects the browser to the paper's parent HTML page. A request for the PDF from that HTML page will then work.

These redirections mean you can see the metadata about papers before clicking on the PDF.

The code uses a list of redirect rules. When I extend this list of sites the extension works with, you will be asked to confirm extending the permissions to new sites. For now, see the github page for more information.
