Features & Capabilities

Firelux is a Chrome extension designed to reduce blue light exposure by applying a customizable color filter directly onto web pages. Users can select the filter color and intensity, set automatic activation hours, and even deactivate the filter on specific websites. The extension operates completely offline, ensuring that no personal information is collected or transmitted.

Easy to configure via its icon panel, Firelux supports Firefox Sync for setting synchronization and provides options for fine-tuning your browsing comfort. For feedback, issues, and feature requests, users can visit the project's Framagit or GitHub pages. This tool is ideal for anyone seeking to reduce eye strain and improve visual comfort while browsing at night or in low-light environments.

User Reviews

Users repeatedly praise Firelux for reducing eye strain, preserving site colors (better than alternatives), and having responsive developer support. Common problems reported by multiple users are occasional sudden failures/crashes and YouTube compatibility issues (blank video or blocked Picture-in-Picture). Overall feedback is strongly positive but tempered by reliability and video-site compatibility concerns.

Pros

Reduces eye strain and makes browsing more comfortable (several users said it helped their eyes)
Preserves website colors with minimal distortion compared with other dark-mode extensions (explicitly preferred over Dark Reader)
Active, responsive developer support—users praised the author’s responsiveness and fixes
Good substitute when switching from Chrome to Firefox; users say it works well as a replacement for similar extensions

Cons

Occasionally stops working or crashes unexpectedly (multiple reports of it suddenly failing)
Compatibility issues with YouTube — reports of blank video display (on Nightly) and interference with Picture-in-Picture

Is Firelux 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.

Firelux 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.

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