Firefox – Open mailto:-links in GMail

This article was been published more than a year ago. The information may be outdated.

I use GMail a lot. I also send a lot of emails, many of those originating from mailto:-links. Hence, it is practical to have mailto:-links open in GMail.
 
This is quickly and simply achieved by going to Tools, Options, Applications. In the search-field, simply enter mailto, then use the Action-field to select GMail, Yahoo Mail or something else, like so:
 

 
Some installations of Firefox do not have the GMail-alternative. This is simply fixed. Open a new tab, then enter about:config in the address-bar. Into the filter enter
gecko.handlerService.AllowRegisterFromDifferentHost, then doubleclick the value so that it is set to true. Then copy/paste the following piece of Javascript to your Addressbar: javascript:window.navigator.registerProtocolHandler("mailto", "https://mail.google.com/mail/?extsrc=mailto&url=%s","Gmail"). When asked whether you want to add GMail as an application, answer “yes”.

    hi,
    thanks for this post.

    Small typo in the instructions, as the line to be entered into about:config filter should be:
    gecko.handlerService.AllowRegisterFromDifferentHost

    peace
