## Description

Invert Colors is a straightforward Firefox add-on designed to invert the colors of web pages, including images, making browsing easier on the eyes in low-light or darker environments. It features a convenient toggle button for quick color inversion. Additionally, users can invert colors globally using the hotkey Alt+Shift+R or just on the active tab with Alt+R, offering flexible control over the browsing experience.

## Review summary

Users praise the add-on as a simple, effective color inverter that eases eye strain and offers an image-exclusion option. Repeated complaints center on inconsistent coverage (many pages don’t invert correctly), unreliable image-exclusion in practice, and issues with dynamic content or fullscreen/video modes; several users also want finer per-site control.

### Pros

- Effectively inverts page colors to improve readability and reduce eye strain/photophobia.
- Option to exclude images so pictures can remain in their original colors.
- Simple, lightweight and easy to use—many users report it “just works.”
- Works well on sites without a native dark mode (users reported good results on sites like LeetCode and Pluralsight).

### Cons

- Inconsistent behavior across sites—several users report it doesn’t work or only partially works on many pages.
- The image-exclusion option can be unreliable; images are still sometimes inverted despite settings.
- Problems with dynamic content or display modes (colors reverting on infinite-scroll pages or failing in fullscreen/video).
- Limited per-site control—behaves largely as an all-or-nothing toggle for many users.
