Good; it It worked on fx14 for me, but i used the .CSV format. (Others have complained that the default xml format didn't work on fx14)
By the way, this should be 5 star, but due to a Mozilla bug, I can NOT SEE the stars on my black screen setup (which i need for my disability. So, i have no idea what rating firefox selects)
