You should not have a problem with gmail are you bringing it up with a bookmark try: http://mail.google.com/mail

Using Google Toolbar features without toolbars - MozillaZine Knowledge Base Google Toolbar is no longer supported by Google in Firefox 5 or newer versions. You can check out the features of the Google Toolbar using the interactive display of the toolbar on Google's site. This article examines what was in the Google Toolbar that Firefox users might have been using and suggests alternatives.

Note: Google Chrome does not have or use the Google Toolbar because, like Firefox, the features are built-in or accessible from the browser by other means such as extensions. Firefox has another powerful tool and that is keyworded bookmarklets.
