Get open tab URLs for window, or load a list of URLs into new tabs on this window.
I really wish the developer would keep this active—it is simple and effective at performing its function, and it has just enough options. It was forked from an extension called 'tab-snap' which was created over a decade ago but stopped receiving updates and eventually broke. This extension, 'tab-save', restored functionality, but, sadly, it hasn't seen an update in some time either. There have been a few forks, but I haven't seen anyone actually making commits, so likely just archiving.
Simple but works, Have some issues bringing up the main dialogue, but going to options/settings of the extension you can click back to go to the main copy place.
