Redirects requests for PDFs of papers at some popular sites to their corresponding HTML index pages.
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 (Website link below) for more information.
