Google Instant now features on Google Toolbar 7 for Internet Explorer 8 and 9. In addition, also introduced a fresh, clean look that personalizes Toolbar with the tools you use most.
To enable Toolbar Instant, visit Toolbar Options and click "Enable Instant for faster searching and browsing." Toolbar Instant works on IE8 and IE9; if you're on an older browser, you can either upgrade your Internet Explorer version.
Once activated, Instant works the same way it does on Google.com. The Escape button on your keyboard takes you back to the page you were on before you started searching. You can also type Alt+G to get to the Toolbar search box more quickly.
Another new feature is personalization on the toolbar -- the tools you use most will remain visible, while others will be moved to a "More" button.
As you discover and use particular tools that help your browsing experience, like Share or Translate, they'll automatically appear on the toolbar, making your most relevant tools easy to access. This personalization is stored only on your computer, so no information is sent to Google unless your usage statistics are enabled. You can learn more about this personalization at our Help Center.
Finally, Google has collected all of its privacy settings on a new options menu tab. It looks like users can choose which "enhanced features" to activate/disable on an individual basis. From a single settings menu, you can decide which of these features you'd like to enable and which ones you'd like to stay off.
The new toolbar is available for download now in English, and will be ready in other supported languages within the next week.
