The "Dark Theme" extensions refer to a collection of browser extensions designed to apply dark color schemes to popular products like Google Search and YouTube. Each one is optimized for a specific product to facilitate effective maintenance and bug tracking. Each extension includes an options page where users can customize their color theme preferences. Please note that some extensions use static themes, while others utilize a dynamic dark theme. In dynamic mode, the extension clones the document stylesheets to feature a dark background with light colors.



  1. List of supported extensions and platforms:

  2. What is the "Dark Theme for YouTube" extension and how does it work?

    This extension is developed based on the popular Youtube Umbra user style but with optimizations for quicker loading times and more efficient resource usage. Users can customize the theme via the add-on's options page. Note that this extension is extremely lightweight as it doesn't consume any resources while browsing non-YouTube pages. On YouTube pages, it consumes significantly fewer resources than Stylish extensions, making it ideal for low-end devices.

  3. What is the "Dark Theme for Google" extension and how does it work?

    The "Dark theme for Google" extension applies a dark theme to Google Search (www.google.com), Google Accounts (accounts.google.com), Google Images (images.google.com), and Google Translate (translate.google.com). Users can customize the different colors of the theme via the options page. You can optionally exclude selective Google products from this extension if you prefer the native dark theme.

    This extension is based on the https://userstyles.org/styles/124403/google-black user-style.

  4. What is the "Dark Theme for Twitter" extension and how does it work?

    The "Dark Theme for Twitter" extension converts the color scheme of twitter.com into a dark mode. Unlike similar extensions, this one utilizes the built-in dark theme of twitter.com, resulting in better compatibility when compared to themes installed via add-ons such as Stylish or Stylus. Users can customize the background colors of all the crucial sections via the options page. Adjust these colors or revert to their default values as desired.

  5. Can the colors used by this extension be customized?

    Yes, the extension initially converts all colors to a charcoal/blue theme, but users can access all the colors from the options page and personalize the dark theme.

  9. Can I add custom CSS rules to extend the default dark theme?

    In the latest version of my dark theme extensions, I've included a new text element on the options page, allowing users to add custom CSS rules. This feature enables fine-tuning of the theme to meet your requirements. Note that this feature is not yet available on all dark theme extensions.

  10. Can I specify a period for my dark theme extension to be active? I like the dark theme to only get enabled during nighttime hours.

    Similar to the custom CSS rule option, the latest release includes a new section for setting a schedule for the extension to be enabled. When the automatic scheduling feature is enabled, the extension checks its current state and adjusts the enabling or disabling status based on IDLE and ALARM events. If you wish to use the action button to disable or enable the extension, the automatic mode should not be active.

  11. I like this extension, but the one thing that bothers me is that it always takes a while to load the dark background for new requests. Is there any fix?

    This extension cannot darken empty documents. The white screen that is shown before the load of the document, is the default browser's empty document view. Most likely by installing a dark theme for your browser the color of this empty document alters
