Comment 6 for bug 1688765

Confirmed. This bug still exists in Ubuntu Artful (17.10) as of now.

Cannot login via OAuth2 (=standard method) because button is unclickable. Major changes to Google account required in order to get basic functionality (sending/recieving E-Mails) with Thunderbird. Lightning (calendar addon) doesn't work either. No workaround for this. Regular people will not be able to get their E-Mail software working.

This needs to be fixed for the upcoming release before the Debian Import Freeze happens in 4 days!

New version of Thunderbird in the Debian repository ("testing" or newer) fixes the bug. Please import, thanks.
