I'm attempting to sync my desktop browser and my android phone. The firefox sync tool takes you through several sign in steps including QR code, login page and then an accounts.firefox.com page with your profile pic and several options to alter the account settings, like primary and secondary email, profile pic, etc. There is no button to complete the sync sign in process. The only actionable buttons are change pic/email/password, disable authentication and delete account. There is no button to complete the sync process on either the android browser or the desktop browser. If you close the firefox android browser tab, it just takes you back to step one with sync.
