Helping people with EasyCharity.net just got easier. Like all Firefox Add-ons, the EasyCharity.net Firefox Add-on is a simple extension that installs within Firefox itself (much like themes and plug-ins); it won't install or run outside of Firefox and it won't slow down your computer. You can easily install it within Firefox to try it, and quickly uninstall it (from the Add-ons preference panel under "tools") if you feel that it doesn't suit you.
About EasyCharity.net: Shop online, make a difference. If you're going to shop online anyways, you might as well help out charity at the same time. It costs you nothing extra, so why not? EasyCharity works with 20 online affiliates, including Amazon, Best Buy, and Newegg, to make helping others easier than ever before.
