We all want to save precious BW and want to weed out the pesky ads.. there is an easy way to do the same using Firefox Extensions.
Procedure:
1. Download Firefox here:
http://www.mozilla.org/products/firefox/
2. Install the Adblock extension (Adblock 0.5.2.056)

3. Now we can start adding any filter to the adblock so that it can start blocking it. Once installed, it’s a snap to filter elements at their source-address.
Just right-click: Adblock: done. Filters use either the wildcard character (*) or full Regular Expression syntax.

Now we are done with installing the extension.
Adding Filters
I use Adblock Filterset.G Updater FX extension for filtering the ads. This save time and makes sure that all ads are blocked.
Filterset.G is an excellent set of filters maintained by G for Adblock that blocks most ads on the internet. In addition, this extension allows you to define your own set of filters that you can add
