There seems to be a few bugs Rated 4 out of 5 stars
I have just installed 0.8.6 and I'm getting a pop up error window every time the options page opens, this window open multiple times. Apart from that it is working okay.
[TypeError: doc.getElementById("rdoF") is null]
It did not do this on another Firefox browser using an earlier version of AniWeather.
The detect location also has a problem in the UK as already mentioned. It won't accept UK but does accept United Kingdom.
