Features & Capabilities

Dark Theme for YouTube™ is a lightweight Chrome extension that applies a smooth and visually appealing dark theme to all YouTube pages, making it easier on your eyes during night-time viewing. It automatically sets a dark mode with a sleek black background and supports both HTML5 and Flash YouTube players.

Features include an in-page switch button for toggling the dark theme on or off conveniently from the top right corner of the YouTube site, and two distinct dark themes. Theme A uses standard CSS techniques offering stable performance, while Theme B employs CSS filters with a stylized effect (note: Theme B may cause some video slowdowns in certain browsers). This extension prioritizes user comfort and performance, ensuring YouTube is pleasant to watch any time of day.

Is Dark Theme for YouTube™ Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Dark Theme for YouTube™ requires a few sensitive permissions. Exercise caution before installing.
