Hi all, I need to edit my Gmail mailto link to have a "/u/1" within it, because my default mailbox is not the one I want to be emailing from when I click a mailto link, but the URL within the settings menu is locked for editing. Is there an INI file or some sort of command line edit I can make please? I have another mailto link saved within Firefox that I need to use occassionaly so I can't use any solution that locks me to Gmail. Thanks in advance.
