Overview
YouTube Guardian — Block Non-Educational Channels
Take full control of your YouTube experience. YouTube Guardian lets you build a personal whitelist of educational channels and blocks everything else — so you (or your family) only watch
content that matters.
Whether you're a student trying to stay focused, a parent managing screen time, or anyone who wants YouTube to be a learning tool rather than a distraction, YouTube Guardian puts you in
charge.

How it works
When you open a YouTube video, YouTube Guardian instantly checks the channel against your approved list. If the channel is not on your whitelist, the video is blocked before it plays —
no 10-second previews, no accidental autoplay. Simply add the channels you trust and everything else is blocked automatically.

Key Features
🛡️ Channel Whitelist
Add channels by name, @handle, or YouTube URL. Only whitelisted channels are allowed to play. All other channels are blocked with a clear overlay explaining why.
⚡ Block YouTube Shorts
Optionally disable YouTube Shorts entirely with a single toggle. Any visit to a /shorts/ URL is immediately blocked and redirected.
🔒 Password Lock
Protect your settings with a password. Once enabled, adding or removing channels, disabling blocking, and changing settings all require the password — making it tamper-proof for shared
devices and families.
📋 Import & Export
Manage large whitelists easily. Import a list of channels in bulk by pasting names or handles, and export your list at any time to back it up or share it.
🚀 Instant Blocking
Built to be fast. The video is paused the moment YouTube starts navigating — no playback window before the block appears.
🔁 Real-time Sync
Changes to your whitelist take effect immediately across all open YouTube tabs — no refresh needed.

Privacy First
YouTube Guardian stores your whitelist and settings entirely within your browser using Firefox's built-in storage. No data is ever sent to any external server. No analytics, no tracking,
no accounts required.
