User Reviews

The add-on has strong support and appealing visuals with useful cinema mode and lighting features, but multiple reviews report serious issues. Notably, high memory usage causing crashes, unreliable YouTube functionality, and intrusive marketing prompts that degrade usability. On working systems it’s decent, but overall it’s divisive due to performance and UX concerns, especially for YouTube-related use.

Pros

Great developer support.
Synchronized Atmosphere Lighting works well.
Provides cinema mode/video darkening as advertised.
Visually stylish UI.

Cons

Severe memory usage and performance problems causing Firefox to slow, freeze, or crash.
Not reliable on YouTube; cinema mode features and YouTube integration can fail or interfere with YouTube UI.
Intrusive marketing prompts and sharing requests (promo content and Welcome Guide) that disrupt the user experience.

Is Turn Off the Lights for Firefox Safe?

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.
