Zotero updates automatically by default. You can also go to the Help menu and select “Check for Updates…” to check manually. Finally, you can install a new version of Zotero over your existing version without losing any data.
If you're currently running Zotero 4.0 for Firefox and wish to upgrade to Zotero 5.0, you'll need to install Zotero 5.0 from https://www.zotero.org/download/ along with the new Zotero Connector.
