Those who have called into our support line would have heard the familiar recommendation of switching browsers from Internet Explorer (IE) to Firefox.
First, let me state that Callfire.com works effortlessly and seamlessly across all browsers. We constantly test our existing and new feature set against all available browsers, desktop and mobiles, to ensure that all our clients have a consistently excellent user experience. For the record, IE is a great browser in of itself, however, in our experience we've found that no two installations are the same. In many cases the browser installation is so tightly integrated with the desktop that it can induce behavior that may be hard to replicate. Firefox, on the other hand, due to its modular design assures a much more consistent, faster user experience. Don't take our word for it, read about it at The New York Times.
In the mean time, if you would still want to use IE, that's quite all right as well, as long as all URLs lead to www.callfire.com, the browser itself is of little consequence (or is it?).
