No, I think they're refering to Mozilla. This has become my default browser in X. It's faster than IE, especially with hotmail strangely enough, and supports all the CSS and DOM standards. For those people saying it is a web designers nightmare, I suggest you take the time to look up the standards at w3c.org. Even Apple has a page at the developer central on how to use Javascript so that it's compatible between IE and Moz. What this means is that if you use the method getElementById() to access DOM elements you can basically code once for IE and Moz. If you keep on trying to use dreamweaver and propietry Javascript, you will have problems as the document.all collection is IE only. You might find that IE5 on the mac (for classic) doesn't display everything the same way as Moz or IE5 for X but on the PC Moz and IE are almost completely interchangable.....
...unless they have outdated Javascript to detect and use NS4
