Yet Another Undo Close Tab di Andrii Volosovych

YAUCT (Yet Another Undo Close Tab) is another add-on that helps you easily reopen recently closed tabs without having to search for them in the history window.

Open the Options page by making context click on the action icon or use the button in the action popup after closing at least one tab.

Here are some cool features:

1. Support for dark, light, or system-based themes according to your OS preferences.
2. Quick filtering for your list of closed tabs by title, URL, or both.
3. Sync your add-on settings across all your Firefox browsers.
4. Open tabs by middle-clicking without closing the actions popup.
5. Great customization options.
