JabRef Browser Extension от Tobias Diez

Browser extension for users of the bibliographic reference manager JabRef.
It automatically identifies and extracts bibliographic information on websites and sends them to JabRef with one click.

When you find an interesting article through Google Scholar, the arXiv or journal websites, this browser extension allows you to add those references to JabRef.
Even links to accompanying PDFs are sent to JabRef, where those documents can easily be downloaded, renamed and placed in the correct folder.
A wide range of publisher sites, library catalogs and databases are supported.

Installation
Normally, you simply install the extension from the browser store and are ready to go. Sometimes, a manual installation is necessary (e.g. if you use the portable version of JabRef). In this case, please follow the steps described in the user manual

Usage
After the installation, you should be able to import bibliographic references into JabRef directly from your browser.
Just visit a publisher site or some other website containing bibliographic information (for example, the arXiv) and click the JabRef symbol in the Firefox search bar (or press Alt+Shift+J).
Once the JabRef browser extension has extracted the references and downloaded the associated PDF's, the import window of JabRef opens.

You might want to configure JabRef so that new entries are always imported in an already opened instance of JabRef.
For this, activate "Remote operation" under the Advanced tab in the JabRef Preferences.
