Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
(All) Added a de localization.
(Thunderbird) Stopped displaying RSS feeds due to the vast number of notifications that were sent. This is only temporary until a delayed system for dispatching notifications is created that will handle a large load of notifications (Growl will actually handle this in 1.1, so it may not be worthwhile)
Added Chatzilla support.
