If you’re using Google Toolbar 5 for Internet Explorer (or Toolbar’s Firefox version), you can add the Gmail custom button to make your life easier. With the Gmail button, you can get new message alerts, see previews of your mail and use Toolbar’s search box to find any message no matter what page you’re on.
Google Toolbar also has a “Send to” feature: when you click on the “Send to” icon, a Gmail compose window opens that automatically includes a link to the page you’re currently on and any text you have highlighted on that page. This makes it easy to email your friends interesting pages you come across as you browse the web.
Plus, you can also add Google gadgets to your Toolbar to bring your favorite websites and online services closer to you.
