We all know the importance of checking our web pages with multiple browsers, especially when we are designing a new layout for a website.
The number of extant browsers we need to check with are enormous:
Internet Explorer (IE) 6,
IE 5.5,
IE 5.0,
Netscape 7.X (ie, Mozilla 1.0.X),
Netscape 6.X (or Mozilla 0.9.X),
Mozilla 1.3.X (and above),
Opera 7,
Opera 6/5,
Netscape 4.X,
IE 4.X and so on.
And then there are the different platforms:
Windows,
Macintosh (Mac),
Linux, etc.
The problem for most people is that multiple versions of certain browsers cannot co-exist with each other, the most notable example of this is IE for Windows. Unless you are privileged to have multiple computers, this presents a certain difficulty for the average webmaster. This article suggests some ways for you to run multiple versions of multiple browsers on one computer.
