There are two steps to installing Zotero: installing the application itself, then adding a browser connector. The word processor plugin will be added automatically with the Zotero application.
The word processor plugin was installed with the application, so you don't need to do anything special.
If you use a Mac and Safari: the connector is installed automatically, so you don't need to add it specially. You still need to enable to extension, though—see the short video below. And if you use Firefox or Chrome you'll need to install a connector the same as others. See also Zotero's Zotero Connector and Safari page.
This video shows how to install Zotero 7 on Windows, and how to add connectors in Chrome, Firefox, and Edge.
The Safari Connector is included when you install Zotero on a Mac, so you don't need to add it specially. But you do need to enable the extension to see the Save to Zotero button in the address bar. Go to Safari's Settings, then Extensions, and look for Zotero to give it permissions. This short video (made by Tim Miller, a librarian at Cal Poly Humboldt) shows how to do that.
If you are having problems installing Zotero, first review the system requirements.
