871246 - [Session Restore] Provide an API for accessing metadata

Status: NEW

(Firefox :: Session Restore, defect)

Description

[David Teller [:Yoric] - still alive but not very active]

Many add-ons seem to rely on the internal data structures used by Session Restore. As we are currently in the process of cleaning up the code and refactoring these data structures, we need to provide public APIs to the same effect.

Opening this bug to determine exactly which APIs we need to expose and what they should look like.

I request an API to tell a tab is restoring or not. Until a tab is fully loaded/restored, the API should return true, otherwise false.

Another API I want is to cancel restoring a tab, after "SSTabRestoring" event but before real restoring/loading.

First, please file separate bugs for any API you want instead of commenting in unrelated bugs. Second, can you elaborate on your use case and why you'd want that? (But please don't elaborate here but in the other bugs.)
