Rated 5 out of 5 stars
Very good and useful addon, but from few day it cannot update the weather data and for this reason is incompatible.
I try using AddOn Compatibility Reporter, but w/o success to make it working!
After decompiling the source as I see the user ID and API key may be not actualized the data provided by weather.com
It's incompatible with Thunderbird 7/8.
Can you please be so kind and provide update for this issue? Will be glad to help in something or rewrite a new addon perhaps World Weather + Revived ;)
