  • Version 2.0.14

    Released Aug 19, 2026 - 247.1 KB
    Works with firefox 121.0 and later
    Improved fact-check accuracy on regular (non-live) videos: when the video's transcript is available, claims are now detected from the full transcript only, with captions used purely for on-screen timing. This eliminates duplicate or fragmented checks that could appear during the first minute of playback. Live streams are unchanged. Also adds the extension version to its config request for smoother update rollouts.
