I saw the website of a friend the other day. This person is a friend and a successful person in her field. Her website was done by a service which specializes in companies which do the same things she does. It was odd to me that the site did not look good in the Firefox browser. In fact, some of the containers or divs were extending out past the main container or wrapper. This was made painfully clear because the white color contrasted with the surrounding structure. This site looked good in Internet Explorer. This is bad. This site design firm had designed this website by checking it in Microsoft Internet Explorer only. But the fact is that the biggest share of the market right now is had by people using Firefox, Chrome and Safari. That means that many people will see this site and think that it is junk, which it is. Business owners beware. The website may be your first impression for many people. People should hire a designer who is careful enough to check his/her work in a number of browsers.
