I don’t know how new these are, but I hadn’t seen them before: Google Firefox Extensions
Welcome to the Google Extensions for Firefox page. Extensions are small applications that you download and install into your Firefox browser to add new functionality. We hope you enjoy these extensions!
They include an ordinary toolbar, a text message sender (U.S. only) and an auto-complete tool for the Firefox search bar.
Whats the logic of a toolbar, when a search bar is part of the out-of-the-box Firefox install?
