Pretty good. One major annoyance for me though is that it replaces the scroll bar with its own version. It makes my system feel more inconsistent than it needs to be. I would prefer if I could toggle this functionality.

I like it

This is what I have been looking for sometimes. Thank you so much for the effort. Let me use it for sometime, and if it doesn't produce much hassle I might consider contributing. Thank you again.

All is ok, exept 2 small triangles near "Search" in Yandex.
(and sometimes "staining black" is too slow)

The extension is amazing. It really relieves the eye strain.

However, one of my most important pages, AzureDevOps, is slightly unreadable due to this extension. Many site elements seem to flash between two different background colors.

Other than that, the Microsoft Docs website seems to automatically select dark mode, and is immune to this extension. Which is a bummer, since I would like a sepia theme, not pitch black.

works consistenly across almost every website imaginable. i only wish i could change the hue of the background, to match my colored dark browser theme.

Brilliant little addon, however I'm wondering if we can somehow enable it on protected pages of firefox such as this (addons page)

It does the job well about 98% of the time. The few times it has issues are with websites that already have built-in "dark modes," but you can easily have the add-on remember not to enable on those sites by clicking its button in the toolbar. It does affect load times of websites, but not by a very significant margin. Sometimes UI elements on certain websites become obscured but can be easily fixed by turning off the add-on for that website.

Overall, the add-on does exactly what it needs to do, with near perfect execution. It's an essential add-on for me now along with uBlock Origin.
