Serious problem with confirming my backup authentication code

Hi everyone, I looked on multiple forums but can't find an answer. I am trying to setup 2 way authentication for the Mozilla extensions account. But i can't get past the "Confirm backup authentication code" part. I get the error: "There was a problem confirming your backup authentication code" Here is the codes that i got (can be public because it's expired and i left 2 of them out): w1bycwwp6w eym2bx8yaj wh5h7c77qv s3snv0ez0x 9aveb72jw1 x8d3rzedah So i copy just one of them, and i get the error. * No im not copying all of them, just one * No i don't have spaces in there * No there is no capitals or anything in there or caps (im copy pasting). It's very odd and i can't upload my application. Please advice. Anyone have some idea? Thank you in advance!
