Cannot log into Firefox desktop on Windows 10 and cannot sync

I am unable to use my Firefox for desktop since the last update. It started refreshing by itself and, upon restart, I tried setting a main password but it never accepted one even though the same password works on Firefox mobile (which I am using right now to write this from an Android phone). I tried Uninstaller and reinstalling again wiping everything but everything I try to login to sync on Firefox desktop I get "Unexpected error" as soon as I type my email (it's not even asking for a password)

Hi,

Looks like you're dealing with a Mozilla account issue. We have direct one-to-one support for Mozilla accounts (which is different from a peer-to-peer support forum like this one).

Please submit a new ticket from this page so our support agent can assist you further.
