Fast Session Saving

Reference

• Bug 630398 - Session store doesn't save session data quickly enough

• Bug 658554 - Undoing a tab pointing to about:blank does nothing

Tabs should be restored when Firefox is killed. The Firefox 4 behavior was that tabs would be saved 10 seconds after the page finished loading. It now will save the tab 2 seconds after the page load finishes.

A closed blank tab should not have "undo closed tab"

Use Cases to Test

Killing Fennec while the page is loading should not restore the tab

Killing Fennec < 2s after page Load should not restore the tab

Killing Fennec > 2s after page load should session restore the tab

Closing a blank tab should not go to "undo closed tab" thumbnail

Test Cases
