Firefox/Mac gets stuck when asking it to send Outlook mail/share Google Drive items
Hi, I'm using a Macbook pro (OS Mojave) & Firefox (80.0.1). I'm having issues when I'm in Outlook365 (web version) and I click the People icon at bottom left to send an email to my Contact Lists. I select a list, and Send E-mail, and the pop up window for Outlook Office 365 opens but there is nowhere to write the email. Just says "Loading" with a spinning wheel. Works with Safari, though.
Same for sharing with Google Drive. When I click Share, it says "Sorry, Sharing is unavailable at this time. Try again later." But it too works with Safari.
This just started happening a couple of weeks ago. I stopped all the extensions. I even threw out the Cookies and Cache, restarted, and refreshed/reinstalled Firefox.
Any help would be appreciated.
