I would like to log in to Firefox sync, but cannot. I choose "I already have a Firefox Sync account. I keep getting a message saying to put this code into the other device. The other device is an iPhone, it tells me to put this code into a pc running Firefox sync. I am going around in circles. I then click "I don't have the other device with me". It asks me to sign in with Account. Password and Sync Key. I do not have the Sync Key. I am told that I can get the Sync Key from my other device. My other device is an iPhone that has no way of showing me the Sync Key, so I am still going around in circles. I have previously reported this but no one from Mozilla has contacted me.
