826782 - Need a notification for first-pb-context-entered

Status: RESOLVED WONTFIX

(Firefox :: Private Browsing, defect)

Description

[Erik Vold [:erikvold] (please needinfo? me)]

Is there a notification of any kind when a private browsing context is entered? or when the first is entered? I didn't see one.

No, and we're not planning to add one.  Why is that useful?

Comment 2

For the SDK we'd like to not break the existing private-browsing module, which has start and stop notifications.

I was going to have the start notification fire when a new window is opened in pb mode, and the stop fired when the last pb window is closed, but with privateHiddenWindows now I'm thinking it would be better to use the "last-pb-context-exited" notification for the stop, and to use a new start notification for the start.

I think that is the wrong thing to do.  Do you have examples of what types of add-ons would just work seamlessly in per-window PB mode if you had a way to expose those notifications?  I think the underlying concept change is large enough that it makes any sort of backwards compatibility in the API error prone or impossible.
