1495194 - Restore Previous Session Button should still be Enabled when Restoration of Session is Default Behaviour on Launch

Status: UNCONFIRMED

(Firefox :: Session Restore, defect, P4)

Description

[stellarpower]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36

Steps to reproduce:

If my default behaviour upon starting Firefox is to restore the previous session, then the restore session button in the hamburger menu is removed, preventing manual restoration.

For example, if Firefox crashes and I don't realise, I use a keyboard shortcut that opens a new window and search a term. As I'm concentrating on the search I want to make, I gloss over the restore previous session dialogue and type in my search term. Now I have permanently lost the ability to recoup all of my important tabs from before the crash


Actual results:

After a crash, if the restore previous session button is closed then

        if the default behaviour on startup is to restore the previous session then it is impossible to recover the previous session because the button does not feature in the hamburger menu

       else the default behaviour is to open a new window / home page, and the restore previous session persists in the menu so the session can be restored manually



Expected results:

The restore previous session button should always remain in the hamburger menu.

Potential issues / scope for further development:

     :: The button may need to restore to the session before the last, apparently Firefox saves the last two sessions (?) so automatic deduction of which is a real session and which is a false start, or manual ability to selestc a session might be useful

    :: Integrate sessions into the history catalogue so that recently closed sessions (cleanly or otherwise) and windows would feature in the history catalogue window much like recently closed windows appears in the history menu. This would enable restoring a window or session of an arbitrary point in the past (subject to limits) easily
