Does what it says - sets the default column layout for new folders.
There is no configuration UI, it is done by editing a comma-separated list variable in about:config. The name is mentioned in the addon's details, but it's not obvious. The process is a bit tricky since the columns are referred to by their code names, but a lot can be inferred from the names and their ordering. The starredCol column is not listed as default. The addon requires manual install from disk.
