Hey! I hope they will implement the dark mode but in the meanwhile you can install dark mode everywhere, at least with Mozilla Firefox and Chrome. I think that for Mozilla it’s an expension to install while for Chrome you need to type chrome://flags in the search bar, search “dark” and enable the option “Dark mode for web content”. It’s still in beta so there can be small problems sometimes with the colors of pictures being reversed, but it’s very rare and works great. Now my entire internet is in dark mode and I can’t go back, it’s a blessing!
There’s also an addon called Dark Reader for Firefox and Chrome. It does a very good job converting a website without dark mode styles to a generic dark mode. You can disable it via a button and exclude websites with a black list.
