Rated 2 out of 5 stars

I elected to install Sunbird since it appears there is no way to hide the calendar on the left pane unless needed (maybe it does, but I want and app that just works without searching for functionality). It sits there taking up a lot of room that I would rather use with my address book extension. It is like having to have the calendar open all the time. I might as well then use Sunbird. When it matures more and allows itself to be hidden and shown as needed, I'll try it out again. After all it is still pre-1.0.

This review is for a previous version of the add-on (0.5).
