I'm not using Internet Explorer 7 at all but I know some guys who like it so much that they may ditch Firefox for it. The new Internet Explorer 7 has basically the same functionality and extensibility as Firefox even though its add-on store is in its infancy compared to that of the Firefox browser.
You can download add-ons for Internet Explorer 7 to add functionality to the browser just like you can for Firefox. The Windows Marketplace lists more than 550 add-ons for Internet Explorer 7. The major difference that I can see is that Microsoft offers free and commercial add-ons for Internet Explorer 7 while I do not know of a single Firefox add-on that is commercial. (correct me if I'm wrong)
IE7 pro is one of those add-ons that everyone can download for free from the company website linked in this sentence or the Windows Marketplace. It adds six new features to Internet Explorer 7, those are: Ad Filter, Super Drag and Drop, Mouse Gestures, Save Page to Image, Quick Switch Proxy and Enhanced Tabbed Browsing Capabilities.
Here is a short overview of what each feature does:
Internet Explorer 7 users should take a look at IE7 pro and test it for a while. It is a free add-on and can be uninstalled without problems if you feel that you do not need the functionality.
Update: The extension has not been updated since 2010. While it is compatible with some newer versions of Internet Explorer including Internet Explorer 8, it does not appear to be compatible with Internet Explorer 10.
Some features that it made available are included in the browser. This includes the spell checker, inline search and other options.
