With Outlook requiring the new sign-in technology, I deleted an account and attempted to re-establish it in Thunderbird. After naming the account and doing the password, said it "Found the configuration...." Selected IMAP then clicked DONE. Got the attached message. I tried using Firefox browser which was my default. Then I made Chrome the default. Same message. "We can't sign you in, Java-script is required" Need some help as to where to go from here. Thanks B
