Background

SeaMonkey allows users to restore previously-closed browser tabs. This preference controls how many tabs you can restore.

[edit]

Possible values and their effects

A non-negative integer indicating the number of tab histories to save for later restoration. Default is 3.

[edit]

Caveats

When this preference is greater than 0, memory will not be immediately freed when closing a tab.
This is a SeaMonkey-only preference. For equivalent Firefox behavior, see browser.sessionstore.max_tabs_undo (and browser.sessionstore.max_windows_undo).
