Features & Capabilities

Midnight Lizard is a powerful Chrome extension that transforms your browsing experience with customizable color schemes across all websites. Choose from predefined options like night mode, dark themes, grayscale, or colorful palettes, or create your own tailored to your preferences. It offers features such as adjustable brightness, saturation, contrast, and hues to improve accessibility and readability. Enhance eye comfort with blue light filtering that shifts colors towards red light without inverting images.

The extension supports website-specific color schemes, scheduling for automatic activation, keyboard shortcuts for quick toggling, and syncing of your personalized settings. It's designed for flexibility, allowing global or per-website application with whitelist or blacklist modes, and optimizing performance with a simplified mode for heavy sites. Open source and community-supported, Midnight Lizard brings a rich set of tools to make web pages more comfortable and easier to read while protecting your eyes during extended screen time.

User Reviews

Midnight Lizard is generally useful for applying dark-mode styling and improving readability across sites, with positive views on its functionality. However, reviewers repeatedly cite customization limitations (no custom color schemes or import/export), lack of per-site toggles, potential performance slowdown, and confusing filter interactions. Despite these gaps, many users find it to be a solid tool for reducing eye strain and achieving consistent dark-mode across websites.

Pros

Improves readability by forcing dark-mode text on websites and enhancing eye comfort.
Functional and generally well-regarded as a practical dark-mode extension.
Gets the job done across many sites and is perceived as a solid overall tool for dark-mode needs.

Cons

Customization is limited: you cannot create or duplicate color schemes, and importing/exporting themes is not supported (only renaming predefined themes).
No per-site toggle or quick on/off control is available, making site-by-site adjustments cumbersome.
Can slow down pages, similar to other dark-mode extensions, impacting performance.
Filter settings can be hard to predict or pinpoint in how they interact, leading to a confusing tuning experience.

Tem conflito com o site NotebookLM que faz desaparecer símbolos matemáticos e faz desaparecer caracteres também.

This extension was recommended to me as a way to force dark text on light background on websites. Well, I tried. None of the sliders in extension config appear to do anything; the predefined themes only have "and add some ridiculous tint all over" takes on "light mode". I thought, perhaps I could make a copy of some "light" theme and try to adjust that? Nope, you can only rename predefined themes, not make duplicates. Ok, then maybe I could export a theme, edit the exported file, and import that back as a new theme? NOPE. "Color schemes import from files is not supported in Firefox." Why is that "import" button even there then?

Is Midnight Lizard 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.

Midnight Lizard requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Midnight Lizard has earned a fairly good reputation and likely can be trusted.
