Extension is completely free and source code is on github and you are most welcome to contribute my friend.
Just to speed things up, open -> choose tab -> close, all from the keyboard itself.
Quickly type a few words from title or url and jump on the right tab.
Hover, single click or double click, navigate the way you like.
Get rid of all those unnecessary tabs after the debugging session ;)
Shows all the tabs from all the windows of current user.
Don't worry about your privacy, this extension doesn't store or send any data.
