Firefox Community Forum

A few weeks ago I purchased a MacMini M4 and am unable to login to sync. MacOS and Firefox are up to date. When logging in to Firefox sync, I enter my email address and then password. I'm then prompted to enter the code sent to my email. I enter the code. I'm then prompted to enter the MFA code from my authentication app. I enter the code. An error shows up that says unable to process. I also deleted the Firefox app and the app data and reinstalled several times. I've tried logging in via Private Browsing. Nothing seems to work. I don't have any extensions installed or other applications or unnecessary processes running.

I have successfully logged into a MacBook Pro, a gaming PC desktop, an HP Windows 11 laptop, and a couple Linux devices and VMs...so I'm familiar with Firefox - been using it for forever. This is the only computer I can't seem to log into. Any suggestions for troubleshooting would be helpful. Thank you.

I can't sebu my google account which I left three years ago and it asks me for veryfiction code with its password but I have password but I don't have phonenumber ples halp me my email address name, [edited] @gmail.com email password, [edited] but i want to recovery access my email or phne number thenks

I tried adding 2FA with two apps (Lastpass Authenticator and Authy). The mozilla account gets added without problems, but whenever I enter a code, Firefox tells me it is wrong. Anything I am missing here?

Our company uses this email address to manage a Firefox add-on. Recently, we lost access to the 2FA device and the backup codes we had. When we tried entering the backup codes, they were unexpectedly marked as invalid.

Is there any way to recover the account using just the email address? We urgently need access to manage the add-on.

I appreciate your help!
