I get a "Mail Server Password Required" prompt, when opening Thunderbird, for an account set to "None" connection security

Staring recently (sometime in the last week or two) whenever I open up Thunderbird I get a "Mail Server Password Required" prompt for one of my accounts. The account in question has "Connection Security: None" and "Authentication Method: Password, transmitted insecurely". I leave the password field blank, check the box for "Use Password Manager to remember this password", click ok and then I'm able to carry on without problems. (Note: for the first day or two, when this problem first appeared, the prompt came up many times throughout the day as I used Thunderbird.)

This account had been working without problems for over a year. Could there have been a recent update to Thunderbird that could have caused this problem? How can I check when Thunderbird was last updated on my system? (I can see from this site: https://www.mozilla.org/en-US/thunderbird/45.1.1/releasenotes/ that the most recent update of Thunderbird was released on May 31, but I don't know when my system was actually updated.)

And most importantly, does anyone have any idea how I can fix this problem?

My System: Windows 7 Professional, sp1, 64-bit Thunderbird 45.1.1, on the release update channel.

Please let me know if any other details would be helpful.

Chosen solution

So I have checked into my account setup and realized that I was mixed up. The email account does have a password, of course. I had thought that it was entered in the anti-virus program we use, not in Thunderbird -- I was wrong about this. So I have solved this problem (it was a unrelated issue).

I doubt you can use an email account without a password. And even if you could it would be a silly idea. "Connection Security: None" has got nothing to do with passwords. Work with your email provider to set a proper password for your account, and then have Thunderbird to remember it.
