IE team 声称需要做到的(大部分集中在兼容性和CSS上):• "Locking" a page to prevent users from accidentally navigating away from it
• Adding a "Find on Page" capability
• Improving username/password management
• Restoring the "Image Toolbar" provided in earlier IE 7 test builds
• Changing the download mechanism, perhaps eliminating the initial download to the "temporary Internet files" folder
• Adding easily editable config files (similar to Firefox's userChrome.css and UserContent.css)
• Enabling draggable tabs from one IE window to another
• Configuring tabs so that each has its own private cookie cache
• Introducing new status bar info, possibly with fields such as "last accessed by user" and "window last updated"
• Enabling add-ons, such as stocks, movies, etc., a la Firefox
可以预料,双方的恶战不可避免.
