AdBan 1.8.1 is a commercial extension now. You must pay $9.99 to use it. Out of my extensions!!!This review is for a previous version of the add-on (1.8.1).
AdBan is free if it was installed before June 2011. Moreover, it can be freely upgraded to the latest versions - see http://www.advertban.com/ff/help#pay_per_upgrade . Email to email@example.com if you installed AdBan before June 2011 .
