2 Solutions for Safari Extension not showing in the Safari web browser

Did you recently installed the Turn Off the Lights Safari extension on your macOS 11 or higher. But you still see no “Turn Off the Lights” in the extension list. Also not after you restarted your Mac computer, and have the latest macOS update installed.

There is a known issue on the Apple side that does not want to show this fresh installed Safari extension. However, there are 2 easy solutions to get it visible in your Safari web browser.

Solution to Safari Extension not showing

macOS 10.15, macOS 11, and macOS 12

The first solution is by installing the Safari Technology Preview, which will refresh the Safari extension list.

The other solution is to run a certain code in your Terminal. That will refresh all the installed Safari extensions. And will solve the Safari Extension not showing in your settings panel.
