Dark mode theme injection for Messenger.com

Messenger.com lacks a native dark mode option, causing eye strain during extended use or in low-light environments. This extension provides dark mode with customizable themes.

User installs extension → visits messenger.com → extension automatically applies selected dark theme via CSS injection → user can click the Charcoal icon in the top-left of Messenger to open a dropdown settings panel → choose appearance (dark/light/system) and theme (Charcoal/Midnight/Deep Blue) → preferences persist across sessions via chrome.storage.sync.

Target users: Messenger.com users who want dark mode / Users who prefer customizable color themes for messaging

Extension source is small and simple (mostly CSS and basic JS), making comprehensive analysis straightforward with high confidence.

Monetization

No paid features detected

All three themes (Charcoal, Midnight, Deep Blue) and all appearance settings (dark/light/system) are freely available without any gating. No payment, subscription, license, upgrade, or billing code exists anywhere in the source. The heuristic 'Stripe' match is a false positive: line 52 of styles/custom.less contains the CSS comment '// white stripe in middle' describing a visual white stripe design element, not the Stripe payment platform.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely as a local CSS/theme injector on messenger.com. It uses only chrome.storage.sync to persist user preferences (theme, appearance) and requires no account, authentication, or external service login. No login-related code, API calls to auth endpoints, or credential prompts exist in the source.

Permission risk
