Zotero Safari Extension Not Showing Up? Here's How to Fix It

Why the Zotero Safari extension disappears

The Zotero Connector saves references from your browser into Zotero. On Safari it ships as a bundled app extension rather than a standalone add-on, so it behaves differently from the Chrome or Firefox version. After a macOS update, a Safari update or a Zotero reinstall, Safari frequently turns the extension off or drops it from the toolbar — which is why it stops showing up.

Step-by-step fixes

1. Open Safari and go to Settings → Extensions. Find “Zotero Connector” and tick its checkbox to enable it.
2. Still in Extensions, select Zotero Connector and set its website permissions to “Allow” for the sites you save from (or “Always Allow on Every Website”).
3. If the extension isn't listed at all, make sure the Zotero desktop app is installed and has been opened at least once — on Safari the connector is delivered inside the Zotero app.
4. Update to the latest Zotero and the latest version of Safari and macOS, then relaunch both. Version mismatches are a common cause of the extension vanishing.
5. Quit Safari completely and reopen it. If the toolbar button is missing, right-click the toolbar → Customize Toolbar and drag the Zotero Connector icon back into place.
6. As a last resort, reinstall the Zotero desktop app to re-register the Safari app extension, then re-enable it in Settings → Extensions.

Skip the browser extension entirely

If the Safari connector keeps breaking, it's worth asking whether you need a browser extension at all. Citebridge captures references into your library without one: connect a source like Instapaper or Zotero, and everything you save syncs automatically in the cloud — no toolbar button to disappear, no per-browser setup to maintain.

You can keep using the Zotero Connector when it works, and let Citebridge be the reliable path that doesn't depend on Safari cooperating. It also pushes your references onward to Notion, so what you save actually lands where you write.
