How do I install the Zotero Connector for Safari?
You can install the Zotero Connector for Safari by downloading the extension (a .safariextz file) from the Zotero download page and then double-clicking on the file. When Safari asks you if you're sure you want to install the extension, click Trust.
In some cases, due to a years-old Safari bug, clicking the Trust button may not properly install the extension. If this happens to you, follow these steps to force Safari to install the extension. (If you're seeing this, you can report the bug to Apple.)
