Recently Closed bởi arielg

Recently Closed is a simple and extremely minimal web extension for a quick access to the Firefox menu items, History ➔ Recently Closed Tabs  and  History ➔ Recently Closed Windows.

A toolbar button that when clicked reopens the last closed tab or window and a right mouse click on that same button to get access to the list of all recently closed tabs and windows that Firefox stored.

― At Your Own Risk ―
The list of recently closed tabs/windows is saved and managed by the browser (Not this extension!) and can be increased by modifying the following browser preferences.

1. browser.sessionstore.max_serialize_back - maximum number of pages from "back" history that can be restored (default 10).
2. browser.sessionstore.max_tabs_undo - maximum number of closed tabs stored/restorable for each window (default 10).
3. browser.sessionstore.max_windows_undo - maximum number of closed windows stored/restorable per session (default 3).

Attention: The Mozilla's JavaScript API, sessions​, restricts the number of retrieved recently closed sessions to 25 at the most. So no matter what values are set in the browser.sessionstore.max_* preferences, the number of menu item sessions will never be more than 25.

Note: I wrote this in a couple of hours, and it's exactly what I need. I'm sure there are existing extensions that offer this exact functionality and with much more options. Shop around if you want or need more.
