Hello, I had to reset my PC tonight and forgot my password for my Firefox account, luckily I have a recovery key. My issue is when I reset my password, the field is missing to enter the key. The recovery instructions state: If you forgot your password and need to reset it, follow these steps. 1. Click the Forgot your password? link on the sign in page. 2. Check your email and click the password reset link in it. 3. Enter recovery key. 4. Create a new password. 5. Create a new recovery key. If I try to enter a new password will the recovery key option appear after? My fear is I would reset my account accidentally and unable to revert afterwards.
