Beta版浏览器的战争：IE 7 beta 2 V.S. Firefox 2 alpha 1 V.S.Opera beta1 [英文]

Beta battle: IE vs. Firefox vs. Opera

Robert Vamosi
Senior editor

Not since the early days of the Netscape vs. Microsoft Internet Explorer browser wars has the development behind Internet browsers been so energized, with developers rushing out new features every few weeks. Forget what's available today, let's look ahead and see what the next versions of Internet Explorer, Firefox, and Opera have in store. One caveat: since all these browsers are still in beta, not all Web sites may display properly, not all ad-ons or extensions may work within the new builds, and the apps themselves may unexpectedly crash or freeze.

	IE 7 beta 2	Firefox 2 alpha 1	Opera beta 1
