I want to add another gmail account to thunderbird, it has accepted the others ones I have created a few years back. When I hit the done button it goes to google account sign in, when I sign in it comes up with a 'Oops! Your browser seems to have cookies disabled. Make sure cookies are enabled or try opening a new browser window. [?]My browser has the cookies enabled! Back in Thunderbird it says it 'configuration can not be verified - is the user name or password wrong'. - It definitely isn't wrong! Any suggestions please? I can use all my new accounts in gmail, but I want to be able to use the Thunderbird account as it is set up on my laptop!
