A new issue has cropped up in Outlook.com email with Firefox. I'm not sure if it is related to the last two updates, but it never used to be an issue before. Lately, when I go to view an attachment within the body of an email using the drop down menu, I get an error message saying that "a plug-in is needed to display this content." I never used to need a plug-in to display attachments within the body of my emails. I always used to be able to view attachments right from within my email window. Now all of a sudden I have to download all attachments in order to be able to view them. This behavior does not occur in Safari. I opened the same emails in Safari, and had no difficulty viewing the attachments within the body of the email. They opened up perfectly fine from within my email window. I do not have to download the attachments to view them when accessing my email with Safari's browser. Is this a bug that I should report? Upon further research, I did not locate a plug-in that is required in order to view attachments within Firefox. To my knowledge, I didn't have any plug-ins before that got removed by accident, so I'm at a loss to understand what is going on here.
