    Maintenance notice (add to listing description, or pin at the top)

    Personal project — not actively maintained

    This extension is a personal port of Filippo Pisano's "Share your Garmin
    Connect workout" Chrome extension, adapted for Firefox. I update it when
    Garmin breaks it and I happen to notice, but there is no roadmap, no
    guaranteed response time, and no support commitment.

    If something stops working, or you'd like a fix, please email me at
