Can you post a full browser screenshot showing what you get? Let test my mac 10.13.6. Did you try Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Did you clear the browser cache? https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

It works for me. see screenshot

I will try your other suggestions....as requested, here is a screenshot of what my Outlook.com page looks like on Firefox.

THANK YOU for your suggestions and help.

....forgot to add the screenshot - see attached file.

Problem still exists in 'Troubleshoot' mode.

THANK YOU for the suggestions, I'll read up on those and try them...

To jonzn4SUSE: Thank you for that scrrenshot but it appears you are using High Sierra and I am using Monterey. Would that make a difference? .

You can try this option, but make sure you have your password. https://support.mozilla.org/en-US/kb/remove-websites-address-bar-suggestions The different OS is not the issue. Your screenshot is soooo widdle!  ;-)

Hi azutkempton, I'm on Monterey with Firefox 103, and outlook loads fine here.

Try this: 1. Go to History > Show All History 2. Right-click on outlook.com and choose Forget about this Site.

NOTE: You will need to log into outlook again.

That worked....THANK YOU, THANK YOU!!!
