Zotero started as a free Firefox extension. You can download extensions and plugins for Firefox, Chrome, Safari and Edge from the Zotero website. There is now also a standalone version that can be used with other browsers, and a web version that can be used on shared computers, like ones in the library or campus computer labs. If you are using Zotero on a public or shared computer, restart when you are done to avoid anyone making changes to your collections.
