Chess Focus

By: vanzsom
Hide distracting elements on Chess.com for a cleaner, more focused playing experience.

Features & Capabilities

Chess Focus allows you to hide various distracting elements while playing on Chess.com so you can just focus on the board.

Chess Focus is fully customizable, hide only what you want. You can hide the following.

– Profile Pictures – Country Flags – Flair Icons – Ratings – Player Names – Player Titles – Moves List Sidebar

The extension also centers the board when the moves list is hidden and allows you to resize the browser to as small as you want unlike Chess.com's Focus Mode that has the board off center and breaks when resizing.

Chess Focus is open source allowing anyone to make any changes they want such as language localization. Available at https://github.com/vanzsom/chess-focus

Also available for Chrome.

Is Chess Focus 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.

Chess Focus requires very minimum permissions.

  • High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.
  • Low ******* ****** ** *** ********* ******** *********
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.

Chess Focus is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
