This add-in duplicates one of the features of IE7Pro, but it's ideal if you just want the tab-handling feature and not the other functionality of IE7Pro.

GooglePreviewIE

Google may help you narrow down your search for information, but wouldn't it be nice if you could get a better sense of whether each site really matches what you're looking for? GooglePreviewIE add-in helps. It shows you a thumbnail preview of each of your search results, so that you'll have a better sense of what you'll visit if you click. It works for Amazon and Yahoo as well. You'll only see thumbnail previews if you use the search box on the GooglePreviewIE tool bar itself. Searching from Google, Amazon or Yahoo—or from Internet Explorer's own search box—won't show previews.

ieSpell

How many times have you been embarrassed by a spelling error you've made on the Web—for example, when creating and sending e-mail from Web-based e-mail sites such as Gmail—or on your blog?

Probably more than you'd like, or more than you even know. Here's a simple solution—get ieSpell. It's a simple-to-use spell checker that integrates directly into Internet Explorer.

It works just like the spell checker in a word processing program and lets you add your own words to the dictionary. Also, ieSpell works anywhere you type in text, including forms, blogs, Web-based e-mail and more.

In addition to checking your spelling, it also will look up definitions in Merriam-Webster online or link you to Wikipedia. You can even integrate the spell checker with your Microsoft Office spell checker so that they share the same custom dictionary.

Leech Video

Frustrated that you can't download and save videos from video-sharing sites such as YouTube, or from other sites such as CNN? Then get this simple add-in. Leech Video installs as a button on your tool bar. Play a video, click the button, and a pop-up appears (shown nearby). Right-click the link toward the bottom of the pop-up, choose Save Video and you'll be able to download and save the video. Note that you'll have to tell Internet Explorer to allow pop-ups or Leech Video won't work.

StumbleUpon

This add-on combines two of the Internet's most popular activities—finding new Web sites and connecting and sharing with others. Install the tool bar and tell it what topics you're interested in, and when you click on the Stumble button, you'll be sent to a Web site that matches your interests. Every time you click the button, you'll be sent to another site related to your interests. For each site you visit, you can click a button saying whether you like or dislike it, and StumbleUpon learns from that and fine-tunes the sites to which it sends you. In addition, as you surf the Web on your own, click a button saying whether you like or dislike the site you're visiting on your own, and StumbleUpon learns from that as well.
