Features & Capabilities

SimpleChessBoard is a user-friendly chess analysis tool available as a browser extension and a web page. It allows users to load chess positions or complete games using FEN or PGN notation. Users can also manually setup and edit positions in edit mode using intuitive mouse controls.

The extension supports browsing game history, testing variations, and displays arrows indicating both the last move and the engine's recommended move. It lists all legal moves, detects checkmate or stalemate, and integrates a JavaScript version of the powerful Stockfish engine for position evaluation. An evaluation graph visualizes mistakes and blunders with color coding.

Users can share or save positions and games via URL encoding, allowing easy sharing with friends. Additionally, it offers the ability to play against the computer, flip the board, and easily navigate through moves. This versatile tool is perfect for chess players seeking quick, interactive game analysis and practice right from their browser.

Is SimpleChessBoard Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SimpleChessBoard does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

SimpleChessBoard has earned a fairly good reputation and likely can be trusted.
