I cannot compose a new message or reply to a message on my Outlook email. I can check/open messages just fine, I just can't compose... I sign in with Firefox every single day and never had a problem. The refresh button blinks heavily while loading after I hit "compose" or "reply" and I think the page is failing to load completely because the message/conversation doesn't show up. I can type the recipient and subject but I cannot get the cursor to show up in the message field. However... when I try with my other Outlook email account, no issues! Then I tried on Safari, no issues. So, I'm unable to compose an email with under my primary Outlook email account on Firefox ONLY. What the heck? Please help.
