I'm on a Mac using T-bird with 5 other mail accounts. Trying to setup Gmail account. Using T-bird auto setup and have checked with manual configuration that okay (or what I think is okay). Authentication set to 0Auth2. Password I'm using is same one that works for webmail. When I hit Done button for set up it takes me to a signin page (see Image-1). When I hit Next it gives me an error page (see Image-2). What am I doing wrong? Thank you.
