Someone gets it – eBay’s recommended browser types are IE 6 or later, Firefox 1.5 or later and, bless them, Safari 2 or later. Safari is the standard browser on the Mac, and an increasing number of people use Macs. Moreover those Mac people tend to be early adopters and (sooner or later) evangelists.
If you are a Safari user, then I recommend downloading the latest version of the Webkit, which is the nightly build of the engine of the Safari browser. It speeds things up a lot…
