User Reviews

User feedback on Dark Reader is mixed but leans positive: it generally provides effective dark-mode with customizable options and aids accessibility. Users cite easy-to-tailor visuals and improved readability. However, several reviews report performance downsides, including browser slowdowns and conflicts with other extensions. Some sites (e.g., Google Docs) may exhibit image inversion issues, and onboarding can be confusing for new users. Overall, the add-on delivers a useful dark-mode experience for many, but reliability and compatibility concerns mean results vary by site, device, and setup.
Pros
  • Works well as a dark-mode solution, with reviewers noting the pages are effectively darkened.
  • Accessibility-friendly features, including high-contrast options that help users sensitive to bright sites.
  • Customizable appearance options (brightness, contrast, sepia) to tailor the look.
  • Some reviewers report that it improves Firefox performance.
Cons
  • Notable performance slowdown and heavy resource usage on some setups, affecting browsing and possibly other extensions.
Recent reviews
The best dark mode add-on there is and nothing else comes close, visually it's brilliant! it dynamically and intelligently changes any page to look great depending on the different sites. I haven't seen one site that looks bad with it. The only problem is the performance hit on certain sites where it causes some slow downs, But it's so good that I don't really mind it that much.

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
