I haven't used Thunderbird for a while but when I started to use it again I found out that I have to give the application the password for imap.google.com. As far as I know, it's the same password as the email's. After I typed the password, I have an error that "login failed".
What should I do?
I'm using ubuntu for a couple of months and I don't know it very well yet!
Thanks for helping! :D
