automaticDark is a Firefox extension that can switch to dark theme automatically on a schedule

Firefox has a really cool native dark theme. You're probably aware of this, but in case you don't know, you can switch to it from the add-ons page: select the themes option on the side bar and click on the Dark theme.

This process has to be done manually every time you want to switch between themes. Windows 10 has a night mode that can be enabled automatically, and when this option's enabled, Firefox will enable the dark theme on its own, and reverts to the default theme when the operating system turns off night mode.

But not everyone uses Windows 10. If you're on a different operating system, and want your browser to switch to a dark mode on a schedule, you can use an add-on called automaticDark. You may also find the add-on useful if you want to enable and disable the dark theme on a custom schedule.

automaticDark options

The extension doesn't have a toolbar icon which means that you need to head to the add-ons page to manage it. The options page lets you set the dark theme at sunset, and switches back to the daytime theme at sunrise. The default options for sunrise and sunset are set to 8:00 AM and 8:00 PM. You can change the time manually, like I've done. That's a pretty useful option to have, since not everyone works during the same hours of the day. There is an option to automatically set the sunrise/sunset time, but if you enable it, you'll be prompted to grant the geo-location permission for the add-on.

There are two more options on the page: these allow you to set the daytime theme and the nighttime theme. You can choose from any of the three default themes that Firefox ships with: Default, Light and Dark. If you're a night shift worker and prefer using the day theme during the night (and vice versa), you can switch them per your requirement.

Once you have set the sunset and sunrise times, automaticDark will enable the corresponding theme automatically. I've been using it for about a week, and it has worked flawlessly. The extension does not change the appearance of websites, i.e., it will not change a page's background to a dark color. If you want that, you should try Dark Reader.

Custom themes support

I don't like the built-in themes in Firefox, so I use third-party themes. Will automaticDark work with it? Absolutely, as long as the theme that you're using is listed in the Add-ons > themes section (and not under Extensions), it should work. The easiest way to check this is right from automaticDark's options page, just click the daytime or nighttime theme setting, and the third party theme that you want to use should be available in the drop-down menu. Set it as the theme, and you are good to go.

On the other hand, I found that extensions which change the appearance of the browser like NightOwl, Firefox Color aren't supported. This isn't automaticDark's fault, it's just that these add-ons use a different method (modified CSS) to change the look of the browser.

automaticDark is an open source extension. The full name of the extension is automaticDark - Time-Based Theme Changer. This is a useful add-on, even for those on Windows 10.

    Kinda gimmicky. This whole “dark theme” thing on browsers and OSes is pretty dumb and a waste of development resources.

    Even Windows versions from 95 up to 7 with the Classic theme allowed you to pick every color for every element of a window. You could create your very own theme.

    Now, at least for Windows, you’re limited to pitch black, or pure white with an option for some dumb accent color and they call that “freedom”. Why take away freedom in the first place? It never ruined anything.

    Same goes for Firefox. Versions 1, 2, 3 and some others allowed extensive UI customization and now it’s been axed to only allow a few lousy button arrangements and picking from some basic themes.

    At least Chrome and its forks were always limited so there is no reason to complain for something you never had in the first place, but the theme support there is just as lousy.

    Bottom line, this whole dark theme is bullshit and people need to ignore it. Pitch black isn’t good looking – it’s strains your eyes just as much as the pure white theme. The best theme would be slight gray background with very dark (but not black) text on top. I can’t imagine of something looking more pleasant and neutral… maybe sepia – beige background and dark red/brown text.

    I use Dark Reader, a FF extension that allows you to extensively customize multiple dark modes (I don’t think they’re technically “themes” in this case). For example, pale sepia on dark brown; more or less contrast; range from colors to monochromatic, etc. You can set different looks to trigger automatically for different websites. You can also toggle the extension on and off (switch from normal to dark mode) with a single keystroke.

    They should extend the dark theme to all pages within firefox like the preferences, about:config, add on listings, etc. They use to have it dark for the new tab when it was blank but not anymore.

    Contrast between web page and browser in “dark theme” is to HIGH an not very pleasant for eyes! Grey browser is much better solution!
