Hello, Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before. Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens Expected behavior: the file should be attached to the email, as it was before. Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead. Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com) This is a regression, it worked in previous versions. Is there a fix planned? Thank you.
