Almost satisfactory. Some issues with the popup menu - the UI behaves strangely when placed in Firefox's Overflow Menu. It either doesn't adapt to the menu's shape, or it forces itself to shrink to match the popup's width, making everything tiny and makes it difficult to change the addon's settings.

So far this is the most effective dark mode add-on I have used (switched from Dark Reader due to it frequently defaulting my FF Theme), though maybe not the most efficient with some sites/pages have some CPU load runaway (CPU used i7 4770k).

会使页面加载速度减慢，出现无响应，但夜间模式的效果非常好，背景和文字配色都很顺眼。

VERY GOOD WORK, i very like it. thanks to the developers for the work, they made a really good job
