OWA (Outlook Web Version) Drag and Drop Not Working with Firefox 99

Since the latest Firefox 99 update, when I drag and drop an attachment into an Outlook Web Access email on Firefox browser, it does not work (can do attachments through the attachment button, but this takes much more time to click, locate file, and attach). This process continues to work on my other browsers (Safari, Chrome). This is very frustrating (making me consider switching my primary browser. Any help with this would be appreciated.
