Living in the UK I am constantly being caught out by unexpected downpours and cold snaps in the middle of summer. But since I found the following site I know exactly when to stay indoors.
http://forecastfox.mozdev.org is the URL you need for this funky little forecasting tool that lets you see the weather at a glance while you are surfing. Clicking the installation link will punt you over to the Firefox add-ons site which is a familiar haunt if you are a regular Click viewer. It houses some essential tools for the popular browser. Just click to add, set permissions if you need to, and by the magic of the internet this neat little tool will be automatically added for your browsing convenience and pleasure.
When you restart your browser, you will need to set up your preferences, including telling the software where you live and how you want the information displayed and such like. Once you click OK, your forecast toolbar will be embedded in your browser window. It is updated as frequently as you have requested from AccuWeather.com, so you need never be caught without an umbrella again.
