## Description

Dark Mode Website Switcher is a Firefox extension that forces websites to use their dark color schemes by default, regardless of your system's theme settings. It utilizes the CSS <code>prefers-color-scheme</code> media feature to invert or change website colors without needing to alter your whole system style. You can toggle dark mode on and off with a customizable keyboard shortcut (default: Ctrl+Shift+B) or via a toolbar button displaying a yellow moon icon when enabled.

Designed for Firefox version 95 and higher, this extension supports websites that offer a dark mode, making browsing easier on your eyes, especially in low-light environments. The add-on is open-source and lightweight, requiring minimal permissions, and can be found on GitHub for contributions. Test it on popular sites like WebKit.org and Emojipedia.org to see the dark mode in action.

## Review summary

Overall this add-on is useful for development and testing and is appreciated for applying dark mode via the prefers-color-scheme standard. However, users repeatedly report issues: no per-site/domain controls (global only); inconsistent behavior across sites or sites where only the settings page darkens; conflicts with privacy features like resistFingerprinting; and occasional site breaks or failures on local/static pages. Many requests include a domain whitelist/blacklist or separate modes; reliability and granularity improvements would greatly boost usefulness.

### Pros

- Helps with development and testing; a time-saver for web work.
- Uses prefers-color-scheme (standard) instead of inverting colors.
- Generally easy to use with a simple global switch; works as described when it functions.
- Positive feedback on Firefox/Linux performance and reliability in many cases.

### Cons

- No per-site/domain controls; global switch only.
- Inconsistent behavior across sites; some pages don't darken or only the settings page works.
- Can conflict with privacy features like resistFingerprinting; may require disabling.
- Occasional site breaks or failures on local/static pages (and some sites like watchnebula.com).
- Requests for per-domain lists/whitelisting/blacklisting or separate modes to apply dark mode only to selected sites.
