YouTube Blocker – Take Back Your Time

YouTube Blocker shows a gentle overlay the moment you open YouTube so you can decide: keep watching or close the tab and do something better. It helps you design your environment—not your willpower—for focus and healthier habits.

✨ Features

On-YouTube overlay UI with two clear actions:
“Watch” (close the overlay) or “Quit” (send a message to the background and close the current tab). 

Reminder (optional): reshow the overlay after a user-defined number of minutes. Works even in the same tab after the timer elapses. 

Task list editor (popup): edit and save your personal “do this instead” list directly from the extension popup. 

Sync-first storage with safe fallback: saves settings to chrome.storage.sync, and automatically falls back to localStorage when sync isn’t available. 

Show frequency controls: shows once per session (tracked via sessionStorage) by default; reminder timing works independently. 

Themes: Light / Dark / Auto (follows OS). Instant preview in popup. 

Multilingual UI: 10 languages (auto-detect + manual switch in popup). 

Built for MV3: minimal permissions (tabs, storage), host permissions for www.youtube.com/*. 

Tech: React + TypeScript, Vite + @crxjs/vite-plugin (MV3 build), typed with chrome-types. 

🔐 Privacy & Data

Your tasks and settings are saved in your browser’s storage (sync with fallback to local). No account required. See the project’s Privacy Policy for details.

📌 Notes for Reviewers / Power Users

Overlay is injected by a content script on www.youtube.com/*; “Quit” sends a runtime message that the background service worker handles to remove the active tab. 

Reminder timing persists via chrome.storage.local (lastShownAt) and works independently of the once-per-session display flag.
