Zotero, the powerful reference and citation manager has just seen some good changes in the latest version 5. See http://www.zotero.org for full documentation.
The key change for me was that the firefox extension is no longer used. Firefox joins Chrome and Safari in using connectors to a standalone Zotero. Zotero handles the update seamlessly, and now that I am used to the new format, I like it... as it gives me flexibility in use of browsers.
