The compatibility issues noted in my ExtremeTech article remain: I still couldn't log in to my Citibank online account, and Yahoo! Mail gener¬ated the same "unsupported browser" notice. But these are just as much issues with those Web sites as with Apple. Both of these sites work completely fine in the Mac version of Safari 3.1. Safari doesn't support ActiveX, so any site that relies on that Mi¬crosoft scripting technology won't work. This is a conscious security choice on the part of Safari's designers. More on that later.



Safari 3.1 passes the Acid2 browser test from the Web Standards Project with flying colors. The test evaluates compliance with HTML and CSS stan¬dards. The Windows and Mac versions both score a 75, the highest score I've seen, on Acid3, which tests DOM2, XHTML 1.0, and some CSS3 compliance. By comparison, Firefox 2 gets only a 53, while Internet Explorer 7 earns only 12 points. Sadly, Opera, gets to about 40 and then promptly crashes-the only browser I've tested that crashes the test.

If you use a Mac at home but a PC at work, Safari for Windows offers a way for your at-work Web to feel more familiar and comfortable.
