User Reviews
Pros
- Reliable and fast; no noticeable slowdown.
- Significantly improves night-time readability and reduces eye strain.
- Better or gentler than some alternatives (gray-toned dark mode) and well-regarded.
- Per-site activation via address bar icon for selective use.
Cons
- Incompatibilities/breakages on certain sites, notably YouTube (fullscreen color inversion).
- Facebook-related UI issues (horizontal scrollbar problems, emoticon display, image inversion).
- Inconsistent theming on some pages and unreliable behavior on some sites (e.g., Amazon).
- Per-site controls exist but are hard or limited; lists/UI editing is non-intuitive or not editable.
- Should auto-disable on native CSS dark themes; settings page is static/not interactive.

Awesome extension. Does not slow down and hold up tabs from loading like Dark Background & Light Text extension which is utter garbage. I'm sticking with Owl forever.

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
