iCab is a Mac-only Web browser loaded with features that offer a viable alternative to Microsoft Internet Explorer and Netscape Navigator. While the iCab 1.8 free preview is fully functional, the browser does not yet support JavaScript or Cascading Style Sheets (this support is anticipated in the "iCab Pro" release which will sell for $29). iCab's strength is its integration with and support of the Mac OS. iCab supports such Mac OS features as OS 8.5 appearance, contextual menus, and proportional scrolling. iCab also supports OS 9's "Key Chain" feature. In addition, iCab also supports HTML 4.0 and recognizes Microsoft and Netscape HTML enhancements such as , , etc. For those doing Web design, iCab can automatically reload Webpages as soon as they are edited in a separate application, eliminating the need to switch to a browser to see the results of an edited Webpage. The current preview version will expire at the end of February 2000, though iCab will offer a free version of the $29 iCab Pro.
