Forecastfox 0.9.7.6 version Rated 4 out of 5 stars
Very nice add-on because the information is right
there when you need it...most of the time. I tried to update the bug web-page but couldn't so I'm doing it here. I set config up so that this process discplayed the data on my Yahoo task bar. It displays for some time and then is disappears...don't know when it goes away but the only way to get it back is to stop/restart FF.
