X-Notifier Won't Check One Of My Outlook Email Accounts

This only happens with my Firefox Browser and i have updated my Firefox

the  X-Notifier works fine with my Microsoft Edge Browser no problem there ?

The outlook.live.com website can't be accessed right now.

At the time I posted... when I tried to go to the website manually/directly... I just got a simple webpage saying that the website was not accessible.   I posted here then forgot about it.  Well I just tested again and X-Notifier now opens directly to my Inbox.
So... that is no longer a problem... for me, anyway.
