YouTube AdBlocker 1.3.0
A quick guide to setting it up in Chrome or Edge
What does it do?
YouTube AdBlocker is a small Windows app that sets up a local browser extension for YouTube. It blocks common ad requests, hides ad-related elements, and tries to skip or speed through ads that still reach the player.
It does
not replace your browser or change Windows settings. It does not edit the hosts file, registry, proxy settings, or browser files. Chrome and Edge simply require you to approve locally installed extensions yourself.
What you need
- Windows 10 or Windows 11
- Google Chrome, Chromium, or Microsoft Edge
- The YouTubeAdBlocker release archive
Step 1: Check the download
Extract the ZIP file somewhere you plan to keep it. Then open PowerShell in that folder and run:
Code:
Get-FileHash .\YouTubeAdBlocker.exe -Algorithm SHA256
Compare the displayed
Hash with the entry for
YouTubeAdBlocker.exe in
SHA256SUMS.txt. If the values do not match, do not run the file.
Step 2: Run the app
Double-click
YouTubeAdBlocker.exe. It creates the extension files here and opens your browser’s Extensions page:
Code:
%LOCALAPPDATA%\YouTube AdBlocker\extension
Step 3: Add the extension
In the Extensions page:
- Turn on Developer mode.
- Click Load unpacked.
- Choose this folder: %LOCALAPPDATA%\YouTube AdBlocker\extension.
- Make sure YouTube AdBlocker is enabled.
Reload any YouTube tabs that were already open. The extension now works in your normal browser profile, and you can close the app.
If you are updating from an older version, click the extension’s
Reload button first, then reload YouTube tabs. Chrome keeps the old extension code active until you do this.
Updating or removing it
To update, run the newer executable and click
Reload on the extension card.
To remove it, open the Extensions page, click
Remove, and delete the extension folder if you no longer need it.
Troubleshooting
The Extensions page does not open
Open
chrome://extensions in Chrome or
edge://extensions in Edge. Then load the folder shown above.
It does not affect an open YouTube tab
Reload the tab after installing or updating the extension. Also check that the extension toggle is enabled.
I still see an ad
Try reloading the YouTube tab first. YouTube changes how ads are delivered regularly, so no blocker can guarantee that every ad or experiment will be caught.
Windows or antivirus shows a warning
The executable is unsigned. Check the SHA-256 hash, scan the archive, and only run files you trust. Do not disable security software or add antivirus exclusions.
That’s it
The release includes the executable, this tutorial, and checksum files to help you verify the download.
