590474 - After self-update the frontmost restored window doesn't show until another restart

Status: NEW

(Firefox :: Session Restore, defect)

Description

[Henri Sivonen (:hsivonen)]

Happened when updating to Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b5pre) Gecko/20100823 Minefield/4.0b5pre and also in an update yesterday.

Steps to reproduce:
 1) Have a lot of tabs open in the frontmost window.
 2) Let Firefox download the next nightly in the background.
 3) Quit Firefox.
 4) Launch Firefox (the update should get installed now)
 5) Open the Window menu and try to switch to the restored window with all the tabs.
 6) Quit Firefox.
 7) Relaunch.

Actual results:
At step #5, the title of the window shows up in the menu, but selecting the menu item does nothing, the window is nowhere to be seen. After step #7, the window reappeards.

Expected results:
Expected the restored window to show up at step #4.

Additional info:
I have multiple profiles, so my startup path includes selecting the profile.

I haven't seen this. Can you still reproduce?

This may be an instance of the random missing windows on Mac issue that seems to have popped up sometime in the last 10 days and affecting a range of Firefox builds.

I'm looking into it now but I suspect it has nothing to do with the nightly, FWIW.

Current bug list: 593032, 589969, 591532, 591176 but likely to be more.
