    The Kendo UI Team has identified a problem with the Popup in Firefox, which affects all Kendo UI Widgets that use it. The issue only manifests itself when the page is scrolled as inability to open the Popup there.

    We have identified the root cause of the problem and all following releases, including internal builds, will be free of this defect.

    The corrected minified Popup script is also available for download as attachment to this post. You can load it right after the combined scripts in order to avoid the issue.

    There is an easy alternative fix with CSS only. Force your desired overflow on the document element, like this:
    .k-ff {
        overflow: inherit !important;

    The selector above will affect only Firefox. Adjust the overflow to your needs (visible, auto, hidden, scroll, inherit).
