Status: RESOLVED DUPLICATE of bug 587400

(Firefox :: Session Restore, defect)

Description

[[e-mail]]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0

When fully closing Firefox, and reopening, pinned tabs are no longer present. This occurs when a new window is opened, that does not contain pinned tabs, and this window is closed after the window containing the pinned tabs.

Reproducible: Always

Steps to Reproduce:
1. Ensure all instances of Firefox are closed.
2. Open a new window. Open a few tabs on varying websites and pin the tabs by right clicking on the tab and pressing 'Pin as tab'.
3. Open a second window.
4. Close the window from Step 2 (Window containing tabs).
5. Close the window from step 3 (Window with no tabs).
6. Reopen Firefox and observe that pinned tabs are not saved.
Actual Results:  
Pinned tabs are not present.

Expected Results:  
Pinned tabs should appear whenever Firefox is freshly opened.

For interest, issue also present in chromium. See http://code.google.com/p/chromium/issues/detail?id=40293 .

Confirmed with Firefox 4.0rc1 on Windows 7.

Also happens on Mac and Linux. I'm wondering if session store is saving the session seeing only the last opened window (ie. since the first window has been closed, it forgets about it -- intentionally).

That is what happens. We helped alleviate it a bit with bug 625016, but we do need to make it better still. Hopefully global app tabs will fix everything.
