Thunderbird doesn't download the latest emails and can't access second gmail account
I've upgraded the Thunderbird to version 31.2.0 and I think that's when my problem started, although I am not sure. I have three accounts on it, two on gmail and one with my ISP. I've been using Thunderbird with no problems in the same configuration for over one year. My main email on gmail does not download all the emails. It downloads one or two emails from a few days ago and nothing more. If I select the account and I click check for messages, it downloads only one email and that's it, even if there are almost another hundred emails more recent. Every time I click on Get Messages and select the account, I get one new message. The second gmail account, although I have the correct password, it tells me "web login required". Even if I properly login via browser to the account, Thunderbird will still not be able to access it and gives me the same message.
Regards, Nick

I found out that Gmail sent an email in relation to attempted login from Mozilla for the second account and it informed that Google blocked the account for that application, because "it does not use modern security standards". I can lower the security of the gmail account, but I will not do it. The first account works just fine and this second account was working fine as well.
I don't get password incorrect error. Google tells me that the password is in fact correct. I expect that Thunderbird is modern enough to support google's security standards. After all the first account works fine (no login errors).
Google have changed their policy, if you have a problem with their password policies, or their apparent intransigence on the use of a web authentication protocol (oauth2.0) for email please take it up with them.
Either you lower security (Actually your not lowering it.), back to where it was before Google changed it to prevent any mail application in the world accessing your account (There are no oauth2.0 enabled mail applications as it is not a mail protocol), or stop using gmail in Thunderbird. There is nothing anyone here can do to change the decisions of the organization that used to have the slogan "do no harm"
