I answered in your other thread, but I'll answer more generally here: for the header, navbar, and footer templates I would recommend the hook parse_templates, since that's always executed just before those templates are rendered.

But the variable you want to use has to be available at that hook, and the timing of the call to the parse_templates hook can change. In the case of $permissions, that is set just after the global_start hook is called, so if some plugin using the global_start hook renders a template, parse_templates will be called but $permissions won't have been set yet so preRegistering it to a template won't work. (That's also why GLOBALS.permissions.pmquota stopped working - using preRegister() instead won't make any difference). But as I mentioned in the other thread, $permission is just a copy of $vbulletin->userinfo['permissions'], so if you use {vb:raw bbuserinfo.permissions.pmquota} in the template, that may work without any preRegistering.
