Block non-educational YouTube channels. Only whitelisted channels play. 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. --- Getting Started 1. Install the extension 2. Click the shield icon in your toolbar 3. Open Manage Channels and add your first educational channel 4. Visit any YouTube video — channels not on your list will be blocked instantly --- Perfect for students, parents, educators, and anyone who wants YouTube to work for them — not against them.
