CloseReview for Forecastfox Weather by keith2468a
Rated 5 out of 5 stars
Next to the spelling dictionaries, Forecast Fox is my favorite Firefox add in. I've used it for years now. I highly recommend it.
(And yes it would be great to have the additional data back, either fully customized, or as a single option for full forecast, and they are working on giving us back at least some of it. Post feature requests here: http://forecastfox.uservoice.com/forums/36457-general )
