Adam Warren (ID: 0000008c6fa4f458) Voted 1 ★ - Updated 12/14/2018 Utter nonsense. The "power saving" changes this extension makes - making white things black - WOULD work... on an AM/OLED display. On OLED displays, pixels that are pure black are turned completely off and don't light up at all, which does save some battery. On phones with OLED or AMOLED displays, you are likely to see some battery savings by doing this. However, on desktop or laptop PCs, the chances of you having an OLED or AMOLED display are very, very, very low. Virtually no laptops have this. Therefore, this extension is total nonsense. Do not install it.
