Rated 2 out of 5 stars
With add-on compatibility checking disabled, this extension can be installed in Thunderbird 7.0.1. However, the panel displays only a 5-day forecast, not the 9-day forecast pictured in the add-on description. Furthermore, captions below the weather icons show Sunny, Partly Cloudy, Snowy, etc. but not the name of the day.
The panel is placed at the bottom of the folders list, and no provision is made for moving it to a different location. I use the Lightning add-on with the Today Pane appearing to the right of the message panel. I would prefer strongly to have the option to place the weather panel at the bottom of the Today Pane.
Alternately the weather panel could be hidden normally and made to pop up by clicking on the status bar icon. Again, no such option is offered. I like the idea of this extension, but the implementation leaves much to be desired. Uninstalling.
