I just reinstalled Windows 11 on my PC and Firefox along with it. I tried to access my school Outlook account on Firefox however I keep getting a 403 Forbidden error when it redirects me to Duo Security. Going back one page displays the error code "Authentication access denied" (also on Duo Security). I have tried: - Restarting my PC, both through windows and through a hard reset - Clearing my cache and cookies - using Troubleshooting mode - Allowing Firefox through my Windows firewall - disabling my firewall - changing networks This problem only appears in Firefox, as I am able to log in on Edge.

Did you try to contact the School about the login issue as looks like they don't recognize your login location there.
