I am a firefox user, ever since I start using it for the first time, I never stopped using Firefox, nor did I used IE or Opera for that matter. But I came across a site that blows Firefox into small little pieces, discrediting it, curiously with heavy arguments and 3rd party studies. Check out Firefox Myths and beware that even if you think you know much about firefox or you love using it this will probably change your opinion. Firefox is not the fastest browser, nor it is the most secure and it does not have less system requirements than other browsers according to this source.
