Now we are going to take a quick look at some of our favourite useful (and not so useful) Firefox extensions. All of these can be easily installed either by using the extension manager as we detailed above, or by simply going to the link for each with the Firefox browser and hitting the 'install now' button.

ForecastFox: Everyone is interested in the weather, and this handy little app makes sure you have it to hand at all times. All you need to do is enter your local weather code (the app includes a handy search tool for discovering this) and you are all set. By default, ForecastFox will display weather icons for the next two days and nights. Placing the cursor over these icons will give you the weather report for that period.

ImageZoom: This thoughtful little application sits in the right click context menu and allows you to zoom images in a variety of ways. Not world shaking, but certainly useful to have.

Googlepreview : Hmm, thumbnails for every result in your Google or Yahoo search pages... Sounds desirable doesn't it? Of course it does. Anything that makes your web searching a little bit easier is great, and this Firefox extension does just that.

Nukeanything: Another nifty little application for the context menu. Nukeanything allows you to, well... Nuke anything by right clicking on it.Want to show somebody something but don't want them to see an objectionable image? Some text you want to get rid of? Nuke it!

This application simply causes the offending items to disappear completely, only coming back when you reload the page. You can use this as a handy way to format hard to print pages before printing, since the 'nuked' items will not print out!

Colorzilla: Now this extension could come in handy for any number of applications. Colorzilla installs as a tiny eyedropper icon in the bottom left corner of the Firefox screen. When you click on it, it converts your cursor to a colour sampling tool which will capture the colour value of any part of the current webpage in one of four different formats. Right clicking on the eyedropper icon gives you the option to copy any one of these formats to the clipboard for importing into your favourite graphics program. This gives you a great way to quickly colour match web graphics without leaving your browser. Colorzilla can also zoom a page up to 1000% to help you in capturing the right tone.
