When trying to login with Google account, Firefox indicates "incorrect password", but it's the correct password.

Hi, Firefox doesn't check your passwords. You'll need to reach out to Google to get help with your issue. Since your question appears to be outside the scope of our support forum, as a moderator, I’m going to lock the thread and mark it as off-topic.
