Google Toolbar for Firefox
After two months in beta Google is officially releasing the Firefox Toolbar with a couple of nifty Firefox-only features. One of these is the addition of Google Suggest, which shows useful query suggestions as you type in the Toolbar search box.
Google also heard from plenty of savvy Firefox users who wanted to be able to reorganize their Toolbar with Firefox’s Customize feature. So in the latest version of the Toolbar, you can go to the View > Toolbars > Customize menu to rearrange icons to your heart’s content. You can even move the search box around!
Personally, I have moved the Google Toolbar Search to take the place of Firefox’s default search to take advantage of Google Suggest.
