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.

You may be able to edit that in the handlers.json file in your profile folder. Close Firefox and backup the file before attempting to edit it.
