    Firefox 1.5.0.3 Vulnerability Update
    Notification: http://isc.sans.org/diary.php?storyid=1327
    Workaround:
    To do so, enter in the URL bar: about:config . This will show a long list of configuration options. Search for 'warn-external.mailto' (e.g. use the 'Filter' option). By default, this value should be set to "false". Click on the line to toggle it to "true" (it will be bold if it is not set to the default).
    Also:
    To completely negate this vulnerability, type about:config into the Firefox location bar and press enter, type mailto, find this line:
    network.protocol-handler.external.mailto
    Right click the line and select toggle (to false), close and reopen Firefox. This will result in Firefox no longer opening your default email client when you click on "mailto" links, but can be easily reversed.

    Settings should be (Use filter bar and type in mailto):
    network.protocol-handler.expose.mailto default boolean false
    network.protocol-handler.external.mailto user set boolean false
    network.protocol-handler.warn-external.mailto user set boolean true
