    Version 1.6.4

    Released Apr 13, 2026 - 58.85 KB
    Works with firefox 140.0 and later
    Reworked popup lifecycle: centralized outside-click dismissal and simplified popup DOM creation; increasing popup creation speed significantly while avoiding duplicates.
    Improved currency parsing/detection to prefer explicit context tokens around $ and accept explicit ISO codes (for example "CAD $" now works and other similar currencies).
    Unify size between selection and result in the popup.
    Update the options in Settings to consolidate them (Settings Page).
    Added new auto-sizing units tablespoon, teaspoon, square yard, CFH, micrometer, nanometer.
    Added better caching system.
    Removed management permission.
    Adjusted the layout of the settings page, takes less vertical space and works better on smaller screens.
    Adjusted red background color in conversion popup for better contrast.
    Fixed a bug that prevented the prefetching of the currency rates, resulting in latency (around 1s) for the first conversion.
    Fix: 24/12 hr toggle not being applied for time conversion
    Fix: some currency detection cases like '0.029' being detected as '29'.
    Fix: Spam-Click Race Condition Bug.
    Fix: popup not showing due to race condition.
