You can apply the theme by selecting it from about:addons -> Appearance, or from Customize mode. It's very helpful if you can test changes to the default theme in the Developer Edition theme, to avoid regressions. See a bug in the Developer Edition theme? Please file a bug in the Firefox::Theme component (and thank you). Then each OS has their own files for platform-specific styling, located here: The main styling for the Developer Edition theme is located here: But it's still worth checking the dark theme in particular if there are new hardcoded colors being added to the default theme.

Note that there aren't many breakages due simply color changes, since this is typically just changing some variable values to match light or dark colors.This is controlled by the devtools.theme pref. In Nightly (or local builds) the DevTools theme defaults to light. By default in Developer Edition, the DevTools theme is dark. Mozilla Firefox browser also comes with native Dark theme mode. It changes colors when the DevTools theme changes. When the Dark theme mode is enabled in a program, it converts the UI or interface of the program into dark colors such as Black or dark gray which reduces eye strain and helps using the program for long time specially at night.This gives it more control than other lightweight themes, which allows it to override a number of CSS variables and other styles. It has an extra stylesheet that's loaded when it's applied - see the CSS Section for more information.Because of this, it's only available (for now) in the Nightly and Developer Edition channels - see Bug 1181721 for more information.Rather than being installed separately, it is bundled with the browser using LightweightThemeManager.addBuiltInTheme.It's different from lightweight themes in a few ways: As a plus, you can define exceptions for webpages you don’t want affected by the changes.The Developer Edition Theme is implemented as a lightweight theme, so it is affected by changes in the default theme.

Please keep in mind that you should leave this section blank if you have no CSS knowledge. Those who are experienced with the CSS language can also configure a global CSS in the “Options” section of Super Dark Mode. In other words, you can build a list of websites that will be excluded when applying the dark theme. Furthermore, it is possible to create a whitelist. For example testing forms is a common source of problems. We avoid cases where we use dark foreground and background colors. I can interact with the sites when the dark theme is force applied. I don't see a flash of white/light colors before the dark theme is applied. Define an exception listĪside from the modern dark mode for all the webpages, you can also configure Super Dark Mode to apply a low contrast or a low brightness theme. I can choose to view website content in dark mode. Moreover, aside from toggling the dark mode on demand, you can also configure Super Dark Mode to activate itself automatically in a specific time interval (for instance, during nighttime). Additionally, you can enable a specialized dark mode for specific websites and pages, be them social media sites, email mailboxes, search engines or shopping websites. The extension applies an elegant dark theme to all the webpages you are visiting. Clicking on the icon turns the dark mode on or off but you can also use the CTRL-Q key combination to do so. As soon as you do so, a new black and white icon is placed in the browser toolbar and all the opened webpages are reloaded automatically. Apply a dark theme to all the visited pagesĭeploying the Super Dark Mode addon in Firefox is very easy, as the browser automatically detects the XPI extension and prompts you to give permission for it to be installed. The Super Dark Mode for Firefox can fix that, allowing you to change the theme to black and improve eye comfort.

However, while the dark mode makes the browser toolbar and other areas dark, it does not affect webpages with a light background. One solution is to turn the dark mode on for the web browser you are using. The best solution to tell Firefox that it should use the light theme instead of the dark is by specifying the GTKTHEME variable prior to launching. It is a well-known fact that the bluish light of the screen can put a strain on your eyes, all the more so when spending time in front of the computer during the night.
