ZMail as default in Firefox Problem

Can you edit the script that sets ZMail as the default mail handler in Firefox so that when you click on a mailto link (espectially one in Zoho CRM) it opens the compose window in a new tab instead of opening it in the tab you are currently working in?

Maybe better still have it open in a small* popup window.

*emphasis on "small" - the current compose popup window for Zoho Mail is WAY too big.
