Firefox is much more secure than IE. Also, if you type Firefox addons in a search engine like Google, you will find a while bunch of neat apps you can easily install that make your online experience more fun and helpful. For instance, you can install an add on called Download helper that will allow you to easily download videos from, say, Youtube. There is also another add on called Tab mix Plus that does a lot of things Firefox does not do by default, like allow you to place your tabs at the bottom, which I prefer. Then, there is always Adblock Plus... the name explains it's function.
