prune

This is awesome extension. It would be nice to have shortcut of turning on/off closing duplicated tab and to be able to make site excepions of closing duplicated tab.

This doesn't seem to work well for me, I am using a workspace to sync my browser across multiple devices, I am guessing every time I close and re-open the workspace it resets the timer to prune old tabs? In any case, I've only ever had one tab automatically pruned despite using this for a couple of months. It's a nice idea though and I'd give it 5 stars if it worked flawlessly on workspaces.

It does what it claims! No more tab clutter -- no more duplicate tabs. Very happy.

Simple and easy to use. Especially useful if you're working on long-term research projects!

Changed my life, searched for at least 6 month for an extension like prune! Many Thanks!

Wonderful in its simplicity. It does what it is supposed to do.
