I've used Thunderbird for years and I have changed password on gmail account many times and normally when I do that, a little box pops up and prompts me to put in the new password - THis time however, I get a page pop up that ask me to sign in to gmail. I do that, and then it goes to https://support.google.com/accounts/answers etc a page that tells you how to enable or disable cookies. I can't find anywhere that gives any info on password change in thunderbird except to delete your password in Appdata ( which i did) then it says a page will pop up asking for password. I can't get that put in password page to pop up ! So frustrating - Please help - Thanks
