How to apply for upgraded permissions

If you want canconfirm, you can add it yourself using the triage request form.

If you want editbugs, email bmo-perms@mozilla.org either:

editbugs implies canconfirm; there's no need to apply for both.

Don't forget to include your Bugzilla ID if it's not the email address you are emailing from.
