The current release emulates all of the basic search functionality of the toolbar, allowing users to easily access almost all of Google’s specialty searches (some of which are not yet supported by the original Google toolbar!) from one convenient toolbar. However, Some features supported by other Firefox extensions are not implemented. If you are looking for AutoFill, you may find the AutoForm or AutoFill extensions useful.
