When emails with attachments are viewed in firefox, the preview function does not display the attachment. It opens the preview window and hangs on "Loading Data" message.
When viewing in Chrome and Edge, the preview function works.
This is true in firefox for attachment types such as image files pf png or jpg and for pdfs. When an image is attached, the image thumbnail is displayed at the bottom of the message window, but the "show" option results as described above.
Is there a setting in firefox that should be adjusted?
