Unfortunately I was not able to get it working properly in TB 60 beta 7 (I installed this add-on for the first time). It was not so easy to sort out how to use it, the below comments helped a lot. My settings in about:config are:

extensions.set-default-columns@clear-code.com.columns
threadCol,flaggedCol,attachmentCol,subjectCol,senderCol,accountCol,dateCol,receivedCol,sizeCol,xspamscoreCol,junkStatusCol

extensions.set-default-columns@clear-code.com.order
threadCol,flaggedCol,attachmentCol,subjectCol,senderCol,accountCol,dateCol,receivedCol,sizeCol,xspamscoreCol,junkStatusCol

But new folders don't have the specified columns in their default view.
