After automatic update, clicking Zotero in Safari has no response.
I have already tried restarting the browser, uninstalling and reinstalling the Zotero Connector, updating the translator, and other troubleshooting steps, but the Zotero extension still does not respond at all when clicked in Safari.

However, I just quit Safari, reopened it, and now it works. There is a line on the page that offers a note ("It may also help to restart your computer in between deleting the app and restoring it, though this isn’t usually necessary."), but no mention of quitting Safari and restarting the browser.
