2) Automatically convert DOI codes on web pages into links (optional)
3) Specify your own DOI resolver URL (useful if your institution provides a proxy service)
4) Generate formatted citations for publications
5) Maintain a history of viewed DOIs

No user data is collected by this extension and no information is sent back to the author.
