CommentBlock is a browser add-on developed by Unhalt LLC, available on the Chrome platform. This free tool aims to enhance your internet experience by blocking toxic comment sections on various websites, including popular platforms like Facebook and Youtube. By simply adding CommentBlock to your browser, you can enjoy a stress-free browsing session devoid of distracting comments and other elements you choose to block.

The add-on offers a user-friendly popover interface, accessible by clicking the "CB" button next to the address bar. Within the popover, users can toggle CommentBlock on or off, customize which elements to block (likes, shares, comments), whitelist specific domains to prevent blocking, and report any issues encountered on specific pages.
