Microsoft Edge can force dark mode on any website – here's how

Dark mode is becoming ubiquitous across mobile and desktop apps, and now the trend is spreading to the web. Growing numbers of websites include the option to either switch to a theme that uses darker tones, or explicitly support dark modes triggered by OS settings – but this is certainly not true of all sites.

To help overcome this, Google very recently introduced an option that allows you to force the use of dark mode all on sites. If you're a user of Microsoft Edge – at least the newer, Chromium-based version of the browser – the same option is available to you.

For the time being, forced dark mode is only available to people running the Canary build – the test version of the browser which is updated on a daily basis. If you don't yet have this version of the web browser, you can download it from the Microsoft Edge Insider website, but it's worth noting that you may find stability problems due to the fact that development is still underway.

You can install the Canary build alongside other web browsers, so there's no need to switch to it on a permanent basis if you don't want to.

Forcing dark mode

With the Canary build of the Chromium-based version of Microsoft Edge installed, it takes just a few steps to force sites to use dark mode. In the address bar, type edge://flags and press 'Enter' to be taken to the experiment settings page. In the search box at the top, type dark mode and you should see an option labelled 'Force dark mode for web contents'.

Click the drop-down menu to the right of this setting and select one of the Enabled options. There are several different implementations of forced dark mode, and you may need to experiment with them to find out which produces the best results for you and the sites you visit.

When you've selected the setting you would like to use, click the 'Restart' button that appears to the lower right hand corner of the Edge window.
