643652 - Wrong tab is displayed after closing "Firefox has been updated" tab

Status: NEW

(Firefox :: Session Restore, defect)

Description

[Mats Palmgren (inactive)]

Wrong tab is displayed after closing "Firefox has been updated" tab.

STEPS TO REPRODUCE
1. select the "Open my tabs tabs from last time" preference
2. open more than 2 tabs
3. select the first (left-most) tab
4. make a software update happen
5. quit Firefox
6. start Firefox
Note: a new tab has been inserted at the end (right-most) showing
      http://www.mozilla.com/en-US/firefox/4.0/whatsnew/
7. close this tab

ACTUAL RESULTS
The tab immediately to the left of the closed tab is displayed.

EXPECTED RESULTS
The first (left-most) tab is displayed.
That is, I want the same behavior as when a new tab is opened with
CTRL+T and then closing the new tab -- it jumps back to whatever
tab was shown at the time the tab was opened.

PLATFORMS AND BUILDS TESTED
Bug occurred in Firefox 4 RC1 when it was updated to RC2, Linux x86-64.

Not managed / controlled by app update.

I believe that the code that handles this is either in Session Restore or possibly in nsBrowserContentHandler.js so moving to Session Restore.

Not directly Session Restore. This tab is opened somewhere else, which overrides what session restore remembers as the last selected tab. Might be something we can do to trick that tab though.
