Instead of simply allowing ctrl+click in the tab bar to highlight and then move multiple tabs to a new window, it has this annoying box that you have to wait to load ALL tabs that you have open. No search bar to quickly go to the tab you want to highlight. You have to SCROLL. And if you click outside that box for it to close, then open it up again, you need to wait for it load everything AGAIN. Doesn't save your place either. So you need to scroll AGAIN. etc, etc.

I needed to highlight about 30 tabs but it only allows up to about 5 tabs to be selected. If you select more then it de-selects everything.

Worst add-on I've ever downloaded. Mainly Firefox's fault for updating in such a way to make my perfect tab add-on "legacy" and as such I was forced to use this one instead.
