A simple edge extension to activate a dark mode to the ecosia search engine. This extension allows to toggle a dark mode to the 'ecosia.org' site  and includes a "new tab" page in dark also.
Ecosia is a search engine that uses the profits generated by your online research to plant trees where the need is greatest. They have a free browser extension for you to save the planet: https://bit.ly/3pcptG2

You simply have to install the edge extension. In the extention popup, you can enable or disable the dark mode.

Please feel free to offer me ideas or let me know about potential issues here: https://github.com/gmirmand/ecosia-dark-mode/issues

    Previously, we use the tabs function/permissions to retrieve the domain name. However, this requires the user to share his history which is bad. So here is a fix to do it in another way
v1.1.4 > 09/04/2019
    Alert message more relevant and a little graphic fix
v1.1.3 > 30/03/2019
    Blocking the extension (and user alerting) if we are not on ecosia.org domain
v1.1.2 > 28/03/2019
    Add preventive alerts
v1.1.1 > 24/03/2019
    Fix some stylish issue due to ecosia update
    Add a Google form in extension popup

We already have ideas such as:
>Switch to allow dark mode to activate itself from a certain time
>Propose to choose activation slots
>Choose the color variables
