Insert picture in email text does not work. When attempting to drag/insert picture into email text, the message "The following files couldn't be attached: filename.jpg. Please try again later." appears. Firefox 133.03 64-bit is up to date on Windows 10. I have not been able to find a solution. The dragged/inserted picture always ends up outside the email text box and cannot be moved into it. What is a solution? Is this something new or do I need to reload Firefox?

It worked last Christmas!!! It is not important now that the holiday is over but would like to fix it.
