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
The URLs of two bugs to which you have attached patches
or testcases; or
The URLs of the relevant comment on three bugs which you
wanted to change, but couldn't, and so added a comment instead.
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.
