I can only guess you are asking about the Thunderbird Master Password although it has nothing to do with preventing access to any emails you have already downloaded. You can read about the Master Password here.

I am on TB latest version 60.5.0 (32-bit)...followed the steps as provided by sfhowes...still unable to make the profilepassword work :( It gets installed but I am unable to set a master password...there is no OK button to save the password that I am entering in the addon settings. Are you able to help?

Sorry no I can't help. I am complete amateur. Only can say that Profile Password and Master Password are two completely different things.

Ok, no worries...yep I am aware of the difference between the two :) thanks for your response.

Instructions for Master Password are provided here, and are available independent of any add-on. ProfilePassword settings are under Tools/Add-on Options.

Thanks for your response. Well, I am not using Master Password. I just can't get ProfilePassword working in my TB. I have downloaded it from here Yep, I have tried both the below navigation to reach the add-on settings but as I said before there is no OK button to save the password that I am entering in the add-on settings window. Tools --> Add-on Options --> ProfilePassword Tools --> ProfilePassword

thanks sfhowes.

After the last update, Thunderbird no longer requires a password be entered to sign into my emails. Hence all my emails are available to whoever opens Thunderbird. How do I get the Profile Password feature back again? This has nothing to do with the Master Password.

I tried the suggestion and it has made no difference.

On startup the username/password couplet box still doesn't appear.

I didn't observe this earlier, apologies; if a message is sent it requires a password to be entered.
