Status: VERIFIED DUPLICATE of bug 622379

(Firefox :: Session Restore, defect)

Description

[Andreea Pod]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; rv:2.0b9) Gecko/20100101 Firefox/4.0b9
Build Identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.0b9) Gecko/20100101 Firefox/4.0b9

The started session should open after a required restart regardless to the checked option to clear history when Firefox closes. Opened tabs are deleted and the homepage is loaded (and eventually a new tab with information about the add-on, depending on what add-on you installed.)

Reproducible: Always

Steps to Reproduce:
1.Go to Tools | Options | Privacy (using Mac Firefox | Preferences | Privacy, using Linux Edit | Preferences | Privacy) 
2.Select Use custom settings for history from the first dropdown. Check "clear history when < application > closes".
3.Go to addons.mozilla.org and install any add-on.
4.When prompted to restart the browser, do so.

Actual Results:  
After restart pages are deleted and Firefox starts a new session listing only about:home page.

Expected Results:  
The session should be maintained even if Firefox is set to clear history on close.
