I always run into this issue that I have a million tabs open and then have to manually go through each to see if I still need it or not. So it ends up being work after work.
That's why I built this little extension to give you an overview of what you have and help you apply bulk actions to them.
If you have some time give it a go, feedback is much appreciated :).
