Email, Exchange, Thunderbird errors when clicking on folders

I get an error every single time I click on a folder, how do I fix it?

To disable the error you are seeing you will need to get to the General Tab:


In Thunderbird : Tools > Options > Advanced > General tab

Thunderbird > Preferences > Advanced > General tab

1) Once there, click on Config Editor...
Click on I'll be careful, I promise!
2) In the search box type: send_client
Look for this line: mail.server.default.send_client_info; Value = true
4) Double click on that line to toggle TRUE to FALSE
Close windows
6) Restart Thunderbird
