The Zotero Connector for Safari is bundled with the Zotero desktop app. (Current versions of Safari don't allow direct installation of browser extensions like other browsers.) After opening Zotero for the first time, you can enable the Zotero Connector from the Extensions pane of the Safari settings (“Safari” menu → “Settings” → “Extensions”, not “Safari” menu → “Safari Extensions…”).

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

Using an iPhone or iPad? You can save to the Zotero iOS app using the Share sheet in Safari and other browsers.

If you find that the extension has disappeared from the Safari toolbar or is quickly appearing and reappearing, delete the Zotero app from Applications, redownload it from the download page, and start the app. Your Zotero data won't be affected.

It may also help to restart your computer in between deleting the app and redownloading.

(To avoid redownloading the app, you may also be able to just compress the Zotero app in Applications (right-click → “Compress “Zotero””), delete the app, double-click the ZIP file, and start the app. You can then delete Zotero.zip.)

If you continue to experience this, let us know in the Zotero Forums.

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

Other differences:

• Gated PDFs may not be saved on some sites (e.g., ScienceDirect)
• It's not possible to right-click on the toolbar button to access secondary translators. Instead, right-click on the page itself.
