Using GMail in Firefox 3

The mailto: links brought up Evolution from Firefox 3.0.2 on my new Fedora 9 installation.  I use GMail.  To change this, I found these Lifehacker instructions.  Everything was already there for GMail except for the preference.  On Linux, choose Edit/Preferences, then the Applications tab.  Scroll down to content type “mailto”.  Select “Use GMail” as the action.  You can check out the details of the actions.  In the address bar, enter about:config, then enter “mailto” in the filter.
