Many people have a particular web browser they feel more comfortable using, and using an alternative browser on another machine can take some getting used to. It may not happen often, but you may be using a different work computer or family member's machine which may be equipped with a default browser such as Internet Explorer or Safari. Although it's not a huge problem if you're killing time, although having applications you are familiar with using will increase productivity in a work environment. 24 Apr 2009
