Even if you're using dark mode your eyes can still hurt by bright images/videos. This addon places a dark overlay infront of everything on the page to dim the brightness.

Toggle Dim (All tabs):
Ctrl + Alt + N (Linux/Windows), ⌘ + ⌥ + N (Mac)
Toggle Dim (Active tab only):
Ctrl + Alt + B (Linux/Windows), ⌘ + ⌥ + B (Mac)
