The Zotero Connector for Safari is bundled with the Zotero 6 desktop app. (Safari doesn't allow direct installation of browser extensions like other browsers.) After opening Zotero 6 for the first time, you can enable the Zotero Connector from the Extensions pane of the Safari preferences.

The Zotero Connector for Safari requires Safari 15 on macOS 11 Big Sur or later.

Due to a macOS bug, you may occasionally find that the extension has disappeared from the Safari toolbar or is quickly appearing and reappearing after a Zotero app update. To restore the extension, delete the Zotero app from Applications and redownload it. (Your Zotero data won't be affected.) It may also be necessary to restart your computer in between deleting the app and redownloading.

We believe this bug is less common in macOS 11 Big Sur and later, so the release version of Zotero includes the Zotero Connector for Safari only for those versions. It's possible to run the Zotero Connector on macOS Mojave (10.14) and Catalina (10.15) by using the Zotero beta, but you may need to fix the extension more frequently after Zotero app updates and may encounter additional instability. (Early versions of Zotero 6 enabled the Safari extension for older macOS versions by accident, but it's since been removed and is again available for those macOS versions only on the beta channel.)

If you have repeated trouble using the Zotero Connector in Safari, you may want to consider switching to a browser with a more stable extension framework, such as Firefox, Chrome, or Edge.

Due to technical limitations of the Safari extension framework, some features available in Firefox, Chrome, and Edge aren't available in Safari:

• Automatic proxy redirection
• Automatic RIS/BibTeX import
• Automatic CSL installation

Save to Zotero and Google Docs integration are fully supported.
