TubeStopper 作者： Plektis

TubeStopper is a password-protected parental control extension for YouTube.
Blocks all content by default and only shows channels you've whitelisted.

How it works:
• All YouTube content is hidden until you as a parent add channels to the whitelist
• Whitelisting one video from a channel whitelists ALL videos from that channel — no need to add one video at a time
• Settings are locked behind a password — kids can only watch what their parents allow them to watch

Features:
• Blocks videos, Shorts, search results, and sidebar recommendations
• Shorts permanently blocked — redirects to YouTube homepage
• Hides the left navigation sidebar (no browsing categories)
• Pauses video playback on blocked watch pages
• Works whether YouTube is logged in or not — no Google account required
• No data collection — everything stays in your browser

Password-protected features:
• Quick-whitelist button for parents looking for suitable channels to whitelist
• Import and export whitelist (JSON)
• Manage Channels tab for bulk operations
• Colour theme selector (11 themes)
• Blocking toggle — quickly enable or disable filtering

Privacy:
• No data leaves your browser — everything is stored locally
• No analytics, no tracking, no network requests
• See our privacy policy: https://plektis.dev/privacy

Currently works on Chrome and Chromium browsers (Edge, Brave).
Firefox to follow.

Note: Browser extensions cannot prevent their own uninstallation. For stronger protection, prevent extension removal using your operating system's parental controls.
