Latest Daily update (Thunderbird replacement) loses all email settings

What is the website for Daily?

Thanks, what's the latest version of Thunderbird anyways since the one I download a few weeks ago was Thunderbird Setup 43.0b1.exe and it no longer worked with GMail which was updated over a Thunderbird I got a year ago.... Wonder is there anything else that will let me read a large gmail mailbox by sorting by sender and by date and when I mean large, I mean there is 300,000 emails and also I noticed with all the desktop clients, when I delete in the client, it doesn't actually delete the mail on the actual gmail.

I actually see what happened, Google basically blocks it from using and logging in to imap on gmail's servers:

We strongly recommend that you use a secure app, like Gmail, to access your account. All apps made by Google meet these security standards. Using a less secure app, on the other hand, could leave your account vulnerable. Learn more.


Google stopped this sign-in attempt, but you should review your recently used devices:
