About ECO Live Chess.com

ECO Live Chess.com fixes a bug on Chess.com where the opening explorer gets stuck on "Loading ECO database" for the entire game, only updating after the game ends. Chess.com uses A/B testing feature flags that can silently disable the ECO opening lookup for your account. This extension removes those flags before the page loads, restoring the opening explorer to full functionality so you can see the opening name update in real time as moves are made.
