Make Gmail the default Firefox 3 Mail Client

By Martin English | August 1, 2008

If you rely on online mail clients such as Gmail then you might like the following tip coming directly from the official Gmail blog that describes how to to make Gmail the default Firefox 3 Mail client (i.e. the mail client that is loaded whenever a mailto link is clicked in Firefox 3.

You’ll need to complete the following steps.

  1. Head over to Gmail and sign in as usual.
  2. Once that is done paste the following line of Javascript code into the location bar of Firefox 3 and hit enter. This will add Gmail as one additional protocol handler for the mailto protocol:javascript:window.navigator.registerProtocolHandler("mailto","https://mail.google.com/mail/?extsrc=mailto&url=%s","Gmail")
  3. A line will appear on top of the screen asking if you want to add Gmail as an application for mailto links. A click on Add Application adds the handler, a click on the X button closes the request and changes nothing.
  4. Now head over to Tools > Options > Applications in Firefox 3 and filter for the mailto protocol.
  5. Use the drop down menu on the right side to select Gmail as the default client for mailto links and make sure to hit ok to confirm the change.

Congratulations, you just added Gmail as the default Firefox 3 Mail Client.

    This is exactly what I'm looking for -- will try and make it work tomorrow!
    I use Gmail for all my email, but whenever I encounter a "mail to" box, my PC tries to install Thunderbird...
    Hopefully, this will stop the problem. Thanks!

    Is there any way to make firefox open the email in a new tab. It currently closes the session which contained the mail-to link when it launches the email. If so this I would use this...otherwise it's not useful. thx
