    Version 9.7.3

    Released Sep 21, 2026 - 1.47 MB
    Works with firefox 140.0 and later, android 142.0 and later
    Fixed Firefox startup and checkout sessions that could remain on “Starting up…”. Partner offers now generate a code directly in the extension without requiring sign-in. At supported checkouts, Checkmate applies the partner code and confirms the actual savings, or keeps your existing code when it gives a better discount. Improved retry and checkout-refresh handling.
