[Tutorial] How To Use Multiple Version Of Firefox In A Computer
Having several versions of a browser is very interesting when you have to develop a web site. Making sure that website performs and looks the same in all popular web browsers is crucial for every web site designer. These problems are very common and made from style sheets, because some CSS rules are interpreted in different ways by Internet Explorer and Firefox. The best way is to have multiple computers and install on each of them a specific version of a browser. But because those computers will take so much space and having a computer just to be able to test your website in different browser is not very economical. There is no alternative but to coexist multiple web browser versions on one computer.
