Master Chess 3D

The extension has a decent user base of 7,000 downloads and maintains a perfect 5.0 rating, though this is based on only 9 reviews which limits reliability. The developer website (w3technic.com) appears to be a legitimate web development company, which adds some credibility. The extension uses Manifest V3, which is the latest and more secure version of Chrome's extension platform.

The primary concern is the lack of transparency in the extension details. Critical information is missing including the actual description of what the extension does, its file size, last update date, and specific permissions. While the security scan shows minimal findings, the absence of detailed permission information makes it difficult to fully assess whether the extension requests appropriate access levels for a chess game. The limited number of reviews (only 9) makes the perfect rating less meaningful as an indicator of quality or safety.

This extension appears relatively safe for general use given the minimal security findings and legitimate developer. However, due to the missing technical details, consider installing it in a separate Chrome profile as a precautionary measure. Monitor the extension's behavior after installation and check if it requests any unexpected permissions. Verify the extension actually provides the chess functionality as expected, and consider looking for alternative chess extensions with more transparent documentation and larger review bases if you have concerns about the limited information available.
