Dark Mode is a browser 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 (dark theme #1), please visit the options page and choose a different theme from the 20 options available. There is also a white-list feature which enables you to exclude a desired domain from dark mode. Simply add domain(s) to the designated area (comma separated) and the websites will be excluded from night mode. In order to report bugs, please fill the bug report form in the addon's homepage (http://mybrowseraddon.com/dark-mode.html).
