I accidentally deleted a gmail account from thunderbird but I cannot reinstall it. If I go to new account, put in the user name and email there are green ticks. When I click on continue I receive a green tick and message 'configuration found in Monzilla ISPDB. But when I click on continue it takes me to what looks like google. The top of that page says 'enter credentials for xxx@gmail.com on imap.gmail.com. Below that is https://support.google.com/accounts/answer/32050?hl=en and a message to check the Monzilla support site for instructions. And the Monzilla page says 'waiting for authorisation in loginpopup' and a blue circle goes round and round.... Help!
