Oh dear, I have two Zoteros...

A few years ago I experimented with Zotero in my browser (Firefox), added a few items, then gave it up and went back to my old way of taking notes. But more recently I decided Zotero was very likely essential and downloaded the app, created an account, started taking notes. But now I have noticed the Old Z in my browser is still there but not growing, evolving as the New Z as an app. I don't know how to kill off the Old Z (login info unknown) without somehow endangering new Z. Halp!

The Zotero in your browser is the Zotero Connector used to save information into your Zotero library while you browse the web. You should not delete it, it is a complementary extension to the main Zotero app.
