Downloading the "Turn Off the Lights" Safari extension on macOS Catalina 10.15.7
TURN OFF THE LIGHTS only supported by OS 11. I use Safari. Could I download Firefox that would allow current TURN OFF THE LIGHTS?

Original Title: Can I download an older version TURN OFF THE LIGHTS 4.3.2 for Catalina 10.15.7 (or an equivalent app)?
