network.protocol-handler.app.mailto is ignored by Firefox 3.6
Using Linux, I have this set in usr/lib/firefox/defaults/preferences/aaa_vendor.js
pref('network.protocol-handler.app.mailto','/usr/local/bin/mailhandler'); pref('network.protocol-handler.expose.mailto',true);
With 3.5 this means that by default all users get /usr/local/bin/mailhandler launched when they click on a mailto: link.
With 3.6 the setting is ignored.
I need a way to set the default mailto handler application for all users (all users') in Firefox 3.6 and I can't find one. A solution which involves going to Preferences > Applications and selecting the mailto application (e.g. as described at http://support.mozilla.com/en-US/kb/Changing+the+e-mail+program+used+by+Firefox) is no use to me.
