Internet Explorer 8: What You Need to Know

Improved Tabs and Address Bar:
For basic browsing, the biggest improvement in IE is its tab handling,For basic browsing, the biggest improvement in IE is its tab handling. It's the kind of feature you may not notice much at first, but it's one that goes a long way toward making your browsing life far easier.
If you commonly use multiple tabs, you'll particularly welcome the way IE handles them. When you open a new tab from an existing page, the new one opens directly to the right of the originating one, and both tabs are given the same color. That way, all related tabs are automatically grouped and color-coded. If you open a new tab from a page that is already part of a group, it will open at the far right of the group, rather than just to the right of the originating tab. It will also be color-coded.
