Last night I submitted PasswordMaker 1.6.1 to
http://addons.mozilla.org. There's a backlog of over 200 extensions waiting to be approved so it could be a while before you get it The backlog is due to AMO sending an email to all extension authors encouraging them to update their extensions to be compatible with Firefox 2.0--the first release candidate of 2.0 was released the other day and now AMO is accepting extensions which mark themselves as 2.0.0+ compatible.
