Our reviewer read version 0.5.6 — the most recent version we have reviewed — and found no malicious behaviour. The version shown here has not been individually reviewed yet.

What our analysis found

Dark Mode, used by 2,000,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites. It comes from a trusted publisher and was last updated in September 2026.

The extension is a legitimate dark mode tool that requires broad host permissions, early script injection, and cross-origin CSS fetching to function properly. All external communications are limited to retrieving stylesheets for theme application or opening publisher support pages, with no data exfiltration, tracking, or unauthorized collection detected. The publisher has a strong reputation (0% malicious extensions), and the ML model’s patterns (e.g., high CSS file count, appendChild calls) are typical for theme engines.

Item	Type	Severity	Description
<all_urls>	Host	Critical	Broad host access — the extension can read/modify content on every website.
Contextual Risk Factors	Risk Factor	High	The following context increases the overall risk: • 10% increase: Early script execution enables pre-emptive content manipulation • 10% increase: About:blank access enables potential sandbox escape vectors

About:blank Access	Risk Factor	Medium	This extension can run content scripts in about:blank pages.

About this extension

A global dark theme for the web.

Read the publisher’s full description

Dark Mode is an extension that helps you quickly turn the screen (browser) to dark at night time. Toolbar button serves as an ON|OFF switch which enables you to easily and quickly turn the extension ON or OFF. If you do not like the current dark theme, please visit the options page and choose a different theme from over 50 available options. There is also a white-list feature which enables you to exclude a desired domain from dark mode. Simply add a domain(s) to the designated area (comma separated) in the options page and the websites will be excluded from night mode. Alternatively, you can use the context-menu item in mouse right-click to exclude desired websites. To report bugs, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/dark-mode.html).

I'm not sure why people are saying it doesn't work, it works for me. A lot of sites already have a night mode and even setting in the computer have dark mode, but this is great for websites that are kind of incompatible with it. Like Mcgrawhill assignments are so bright and I have a brain injury and am super light sensitive so this actually helped so much with it. If you were using like on a shopping website it will basically invert colors but I'm super grateful to have it for everything else.

Not the best and definently not the easiest to use either but also not the worst either.I wish that it made the google docs paper become black as well
