Set Gmail as default email app in Firefox 3.0
Tuesday, June 24th, 2008
Mac users who want to use Gmail (or some other webmail service) as their default email app rather than Mail.app already have at least three ways of doing it.
With the launch of Firefox 3.0, there is now another way for Firefox users.
All you have to do is enter the following text into Firefox 3.0’s address bar and hit return:
http://javascript:window.navigator.registerProtocolHandler(”mailto”,”https://mail.google.com/mail/?extsrc=mailto&url=***”,”GMail”)
This will register Gmail as the default handler for any mailto: link you click on in Firefox. Of course it doesn’t work for mailto: links in other apps—say, a web archive or note in Yojimbo.
To undo it, just reselect Mail.app as the default in the Applications tab of Firefox’s Preferences.
For a comprehensive solution, you still can’t beat Webmailer 
which is easy to use and free.

Webmailer is a System Preferences pane that offers a quick and easy way to set a variety of webmail clients as the default handler for composing new messages from mailto: links.
