It's a mystery why Microsoft took so long to introduce tabs to IE, but now that it has, it's leapfrogged the competition. It's simple to launch, close, and rearrange tabs. Unlike all the other browsers in this roundup, IE7 does not put an "X" close button on every tab that's open, just the active tab. Move to a new tab and the X comes too -- an elegant and space-saving way to manage multiple tabs.

Better yet is the Quick Tabs feature, which lets you display all your tabs as thumbnails on a single page. Click any thumbnail to go to that tab; click its X to close it.

Tab List is another useful tab-navigation tool. Click a button, and it displays all of your opened tabs in a list, with a check box next to the live one. Click one you want to visit, and off you go.

You can also save groups of tabs as a Favorite. Use this feature to open groups of news sites you like to visit, or sites related to a special interest, such as digital photography. All you need to do is open all the sites in separate tabs, then save them as a tab group in the same way as you'd save a single favorite. Then you can later re-open them all at once.
