Good start, but very few settings

Doesnt detect accent color in firefox 88.
someone knows how to fix it?

I love this one, I'm amazed that vanilla Firefox doesn't include the chosen Windows color theme at all, this addon was kind of needed really

Native Dark is the best theme, period. It's the holy grail of themes, the colors are infinitely configurable so it can be ANY THEME YOU WANT. (assuming you don't want to add any silly graphics, that is...)

not working on ff70

it was a really good extension until firefox 70. I have a dual monitor setup and firefox is on my main monitor, and as soon I focus on my second monitor, the top bar switches to the light theme. Any chance that this could be fixed?

The only tiny issue I have with this addon is, I have Windows 10 set to cycle my wallpaper, and to automatically change the accent color based on the current wallpaper. When this happens, the rest of Firefox does not change until I click off and then back on it. It's not a huge problem, as I switch windows all the time anyway, but it's noticeable.

One star for deceptive and confusing title. If you just want a static dark theme there are plenty of simpler and better alternatives.
