Dark Mode (WebExtension) от Bernard

Dark Mode is an add-on that helps you quickly turn the screen (browser) to dark at night time.

Toolbar button serves as an ON|OFF switch which enables you to easily and quickly turn the extension ON or OFF. If you do not like the current dark theme, please visit the options page and choose a different theme from over 50 available options.

There is also a white-list feature which enables you to exclude a desired domain from dark mode. Simply add a domain(s) to the designated area (comma separated) in the options page and the websites will be excluded from night mode. Alternatively, you can use the context-menu item in mouse right-click to exclude desired websites.

To report bugs, please fill the bug report form on the add-on's homepage.
