User reviews

Users appreciate the add-on for its simple and effective screen dimming capabilities that aid eye comfort and battery saving. Its customization features like site whitelisting and timing settings enhance usability. However, the new 'auto dark' feature causes dissatisfaction by disabling the add-on on dark-themed sites, prompting some to revert versions. Occasional delays in activation and limited effect on browser pages are minor drawbacks. Users also desire improved keyboard shortcut functionality for quicker toggling.
Pros
  • Effectively dims screen brightness for comfortable viewing especially in dark environments or at night.
  • Allows customization such as whitelisting sites and adjusting brightness levels per site.
  • Simple and easy to use compared to more complex alternatives.
  • Includes useful features like timing (morning/evening modes) and keyboard shortcuts for brightness control.
  • Helps reduce eye strain and can contribute to battery savings by allowing lower hardware brightness settings.
Cons
  • The recent 'auto dark' feature disables the add-on on dark mode sites, which users find undesirable and have downgraded their versions because of it.
  • Sometimes the add-on doesn't activate immediately and requires a page refresh to work properly.
  • Does not affect browser settings pages, limiting its scope.
  • Lacks a keyboard shortcut to enable/disable the add-on per webpage, which would improve usability for keyboard-heavy users.
