Features & Capabilities

The YouTube Dark Theme Chrome extension offers users a seamless and highly customizable dark mode experience for YouTube. Built on top of YouTube's native dark theme, this lightweight extension enhances visual comfort by applying a dark charcoal and blue color scheme without the performance overhead associated with traditional theme injectors like Stylish or Stylus. Users can effortlessly toggle between light and dark modes using the action button, schedule theme activation during specified periods, and tailor the default colors to their preferences. Additionally, custom CSS injection allows advanced users to modify font sizes and styles for a personalized browsing experience. Unlike other dark theme extensions, it modifies YouTube's global cookies and CSS variables to efficiently implement changes, ensuring smooth performance and compatibility. Importantly, this extension respects user privacy by not transmitting any data to servers.

User Reviews

Users appreciate the add-on's effective YouTube dark theme with good customization options and its ability to convert mobile YouTube to dark mode. However, multiple reviews highlight issues including instability when using Firefox containers, failure to work in private browsing, continuous refresh loops on YouTube Music, and a non-functional toggle button. Additionally, the configuration page not being dark frustrates some users. Despite these bugs, it remains favored over other similar extensions by some.

Pros

Provides a dark theme for YouTube and other related sites, helping reduce eye strain.
Highly customizable compared to other similar add-ons.
Effectively converts YouTube mobile to dark mode.
Some users find it better than other dark mode extensions.

Cons

Unreliable when used with Firefox containers, often disables the dark theme automatically requiring reactivation.
Does not work in private browsing mode.
Causes YouTube or YouTube Music to refresh continuously, making the sites unusable.
Extension button toggle does not function correctly or reflect the actual state.
Configuration page itself is not dark, which is inconsistent and bothers some users.

O tema realmente funciona e o YouTube não fica branco estourando meus olhos, só acho que poderia ser totalmente preto a cor e o símbolo do YouTube branco, ficaria mais maneirinho

Is YouTube Dark Theme 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.

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

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
