< Feedback on DuckDuckGo Settings Changer
Never mind, it works, just had to clear cookies for DuckDuckGo, great script :)
When changing settings in the script, they have zero effect on the actual site.
No matter what I do, it stays in white mode instead dark.
The default settings of the script (which are better than nothing) do work.
