The macro https://developer.mozilla.org/en-US/docs/Template:B2GOnlyHeader2 takes the following values as arguments: "web" || "web+" || "privileged" || "installed" || "certified" The message text links to https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Security/Application_security which defines "web", "privileged", and "certified", but not "installed". Therefore, this page https://developer.mozilla.org/en-US/docs/Web/API/PushManager is confusing because it uses "installed", which is not defined on the linked page.
I'll grab this. I've already emailed Jeremie about it. I'll see what he says and tweak the macro so it makes sense. I'll probably clean up some other docs related to this too because it has been kind of screwy for a while and it's been on my list.
I know that Chris has reworked these messages last year. Chris, Janet, can we close this bug?
I think it can be closed now; I've changed the link to the App Security page, to point to https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Security/Application_security#App_Types which is the specific part that defines the app security levels. And I've added a description of "Installed App" to that part.
Teoli, you might want to check that the French translation link is correct, and add a description there too. Thanks!
Looks good to me.
