When using the Document360 widget in the Firefox browser, dragging the widget does not respond in a standard way. Instead of the widget moving while the mouse is being dragged, a ghost version appears to move, and the actual widget only starts moving after the mouse button is released. Clicking again stops the movement. This issue is specific to Firefox and does not occur in Chromium-based browsers such as Chrome.
While this does not block usage of the widget, it affects the overall interaction quality and user experience for readers accessing the widget in Firefox. Improving drag handling consistency across browsers would help ensure a smoother and more predictable interaction.
