Features & Capabilities

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.

Please note that this extension is currently incompatible with Firefox on Android due to limitations in the browser's API. The project is open-source and hosted on GitHub, encouraging contributions and improvements from the community.

User Reviews

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.

Is Invert Colors Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Invert Colors requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
