Can't open outlook online

Hi there,

I have problem to open my outlook online, office.com with Firefox latest version (88.01). I can open it on Chrome without any problem. I have the macbook pro with M1 chip. MacOS updated to latest version. Any idea is welcome. Thank you in advance.

Hello shuzihank


I use this same version of firefox, and I can use outlook without any problem, but if you are having this problem, I suggest you try to reinstall firefox, remembering that this problem may be on your computer and not on firefox.

Hi shuzihank, that's not a very useful error message, is it.

Does that occur before the sign-on screen, during sign-on, or when redirecting back to the Inbox?

I know some features of the site don't work properly without cookies and local storage being fully enabled. For example, because I use the "Delete cookies and site data when Firefox is closed" setting, I needed to create an exception (using the button to the right of it) for the various Outlook sites (outlook.live.com, outlook.office.com, outlook.office365.com).
