Nifty, free <a href="http://www.pcworld.com/downloads/file/fid,23160/description.html">Firefox</a> add-on Email this! is great for anyone who wants to share Web page URLs with others via email software. When you're on a Web page whose URL you want to share with someone, click a button, and the add-in launches your default email client--whether it's a desktop mail client, such as Microsoft Outlook, or Web-based one, such as Gmail--creates a new mail message, and inserts the URL into the body of the message, and the title of the page into the subject line. At that point all you need to do is fill in the recipient's address, type in any message you want, and send off your email.
