Regression: Folder drag-and-drop broken in Synology File Station (DSM 7.2.1)

Description: For the past few versions, Firefox has lost the ability to upload folders via drag-and-drop into Synology File Station. The Issue: Dragging a folder into the File Station interface used to work, but now it is no longer recognized or fails to parse the directory structure. Comparison: This feature continues to work perfectly in Chrome, suggesting a recent regression in Firefox's handling of webkitGetAsEntry or related directory APIs. Note: This is specifically about the drag-and-drop action, as the native "Upload" button has never supported directory selection. Environment: Browser: Firefox 150.0.3 (and several recent prior versions) Server: Synology DSM 7.2.1 OS:Windows 11 ''Moderator note: This question has been edited to correct the formatting.''
