Internet Explorer Subtitute

We have been using Microsoft Internet Explorer for a long time now and it has made its name in internet browsing. But now i came across a better browser and it is called Mozilla FireFox, why is it better? its faster, safer, and eats less system memory(less memory usage means faster Pc). I've been using it for about a year and wow, i think its the best. it has the feature of Microsoft internet explorer and it offers more, try it and compare the speed in browsing, and security(some viruses targets IE. so meaning firefox is safer). it also has lots of plugins and addons that will make your internet experience better, one example is the Download helper it helps download videos from youtube and other video streaming websites (you dont have to install a separate downloader that will eat memory). just go to tools and then addons, and another thing it has themes to make your browser look cool or fit your mood.. heres a link MozillaFireFox Enjoy!!!
