Hello there! My name is Bilal and I synced my Firefox account to my other mail [email]@gmail.com. I enabled the 2F Verification and used an authentication app on my old mobile phone. My mobile phone got busted and I also don't have the backup codes. Would you please help me with this and provide me a solution to lg in back to my account because there are a lot of passwords etc. in my account. I do have access to my gmail account, so if you need any kind of verification, please do.
