Each browser has advantages and risks depending on how they are used None of them is any safer than another despite the anti-MS propaganda. For some types of web based applications Firefox works better, for others IE works best. For browsing IE, Firefox Chrome, Opera will work well and each has their specific features that some like and others don’t. Having multiple browsers available on the desktop is not a bad idea.
I’ve heard that IE is more “integrated” with windows and has access to places Firefox does not. That means that if someone can exploit it, they can get into more sensitive places in your computer and do more damage.
Is this anything you’ve heard about?
