It is a very good addon! Pleasure, update for Seamonkey 2.6.1!

This review is for a previous version of the add-on (2.0.2.1-signed). 

Full compatibility with SeaMonkey 2.6 will be available in version 2.0.4. Meanwhile, version 2.0.2 is now marked as compatible, to facilitate updates, despite a known issue with opening multi-page MAFF archives.
