Features & Capabilities

whyEXT Dark Mode adds a lightweight per-domain “dark style” toggle for websites you choose. It works per domain (not per-tab): you decide which sites are affected, and everything stays local on your device.

What it does

Toggle a simple dark style for the current website’s domain from the extension popup.
Remember your choice locally (no accounts, no cloud sync).
Open the Options page to review, remove, or clear enabled domains.

How it works

Applies a page-level visual style intended to make many sites easier to read at night.
Results can vary by site: layout, embedded media, and a site’s own dark theme can affect appearance.

Privacy

No telemetry, no analytics, and no remote code execution.
Stores only the settings required for functionality (for example, your enabled domain list).

Permissions (why they exist)

Broad website access is requested so the extension can apply styling on normal web pages you visit, after you enable the toggle for that domain.
Tabs / scripting are used to keep styling consistent as you navigate, switch tabs, and reload pages.

Is whyEXT Dark Mode 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.

whyEXT Dark Mode requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

whyEXT Dark Mode is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
