  • Latest version

    Version 2.12.0

    Released Aug 8, 2026 - 344.78 KB
    Works with firefox 115.0 and later
    Steadier analysis while you play, and a new setting for page reloads.

    New
    Choose whether analysis resumes after a page reload

    Turn it off in the popup if you'd rather start each page fresh.

    Improved
    Lighter on your browser during a game

    Analysis does less work between moves, so game pages stay smooth.

    Fixed
    Opening the popup no longer clears the arrows

    The board used to blank and re-analyse every time you opened the extension.

    Fixed
    After a rematch, review opens the game you just played

    It could still offer the previous game until you reloaded the page.

    Version 2.11.1

    Released Aug 6, 2026 - 337.79 KB
    Works with firefox 115.0 and later
    Review any finished game for free, straight from the Chess.com game-over box.

    New
    “Review on ChessSolve” button when your game ends

    When a game finishes on Chess.com, a new button appears right next to Rematch. One click opens that game on the ChessSolve analysis board with every move already loaded — free and unlimited, so you can go over your game even when Chess.com's own review is locked behind their membership. It opens from your side of the board, so if you played Black you see it the way you played it.

    Improved
    Installing is now one click from the Chrome Web Store or Firefox Add-ons

    We removed the manual ZIP download. Sign in with Google could never work on a copy installed that way, so it only led people into a broken sign-in. The one-click store buttons on the download page are the way in.

    Improved
    Saved games link back to the original game more reliably

    Chess.com changed the web address format for live games, which meant some saved games lost the link back to the original. ChessSolve now finds the game's ID from the page itself, so the connection holds.

    Fixed
    The extension popup opens at the right size again

    The popup could open stretched to full width with all the controls squashed into a narrow strip on the left. It now always opens as a properly sized panel.

    Fixed
    Saved games show both players' names

    Games saved to your account were being stored without the two usernames. New saved games now record who played, so your game list is easier to read.

    Fixed
    Shared analysis links no longer come up blank

    If a shared board link contained a move the board couldn't read, the page failed to load at all. It now loads the game up to that point instead.

  • Version 2.10.3

    Released Aug 3, 2026 - 334.42 KB
    Works with firefox 115.0 and later
    Clearer sign-in — the extension now tells you exactly why a login didn't work.

    Improved
    Email verification works the same everywhere

    Signing in with an email and password now asks you to confirm your email first — the same way in the extension and on the website. Signing in with Google is unaffected, since those accounts are already verified.

    Fixed
    Sign-in errors now tell you the real reason

    If a sign-in didn't go through, the extension used to always say “invalid email or password” — even when that wasn't the problem. Now it shows what actually happened, like needing to verify your email first, so you know exactly what to do next.
