Simply One Tab

This extension was create by frustration with OneTab. This extension clogs one tab with links from much time ago and there was no way to remove the oldest entries. It tries to do the same as OneTab and the functionality is basically the same.
Click the button on the extension at it will close all your tabs and opens a new pinned tab with a list of the closed recent tabs. Differently from OneTab it maintains a single list of links with no duplicates in it.
