🖱️ How to Use

Install the extension from the Chrome Web Store

Go to the comments section on any YouTube video or Shorts page

Click the block button next to the author’s name

All comments and replies from the blocked author will instantly be hidden

To unblock, open the extension popup and click “Unblock”

🔒 Privacy Protection

Only the blocked author names and a randomly generated browser user ID are stored

No ads, no tracking scripts, no access to other websites

Data is used solely for maintaining the block list

⚙️ Notes

If YouTube’s internal structure changes, the extension may temporarily stop working

Works on a per-browser user ID basis, so blocks may not sync across different browsers or PCs
