1387337 - Add support for not yet restored tabs after a restart of Firefox (sessionstore enabled)

Status: RESOLVED INVALID

(Remote Protocol :: Marionette, enhancement, P3)

Description

[Henrik Skupin [:whimboo][⌚️UTC+1]]

With sessionrestore enabled not all the tabs are getting restored after a restart of Firefox. Instead it will only be pinned tabs and the currently selected one. All the other tabs are still shown in the tabbar but do not have a contentBrowser attached. This will happen once such a tab is getting focused.

Marionette currently fails in handling those tabs because we always assume that a contentBrowser is available. 

Also see bug 1351940 which is for puppeteer, and which retrieves the tabs by checking the tabbar itself. But getting a window id fails.

browserless tab support exists for quite some time.
