T-Mobile,

Loyal customer hear since VoiceStream and Aerial days.  It’s very frustrating that a tech company hasn’t yet addressed compatibility with login to my Tmobile account via FireFox [latest version 93].  I’m in it right now typing this, however…

it absolutely hates:

https://account.t-mobile.com/signin/v2/

https://www.t-mobile.com/signin?

I’d loved to see this fixed, instead of timeout or messages like we must have got our wires crossed.  Thank you.

Had the exact same issue this afternoon, using the T-Mobile Home Internet 5G gateway. Happened on Chrome, Firefox, and Edge.

Ended up using a phone hotspot to log into T-Mobile.

This evening, things appear to be back to normal.
