Accurate, Yet Strangely Unreliable Rated 2 out of 5 stars
For the short time I had this add-on installed (about two or three weeks), it proved to be accurate in weather forecasts, but it hardly ever worked. 75% of the time, no matter where I set it to be displayed on my browser, nothing showed up. Not wishing to only know the weather some of the time, I uninstalled it and gave Forecastfox a try instead. It's just as accurate (and maybe even a little more so) and works 100% of the time, so that is what I'll be using from now on instead of 1-ClickWeather.This review is for a previous version of the add-on (1.1.4).
