Close Inactive Tabs by Nic Z

If youre like me and you leave millions of windows open with even more tabs per window because "Youll get to it eventually", then this is the addon for you.

This addon silently discards those tabs that you havent used for more than a configurable number days (90 by default).

And it gives you a warning when a tab has been inactive for a long time, that its going to be deleted soon (also configurable).

The addon button, when clicked, will show you which tabs are currently in the "inactive" list and are close to being deleted
