eugh what....this is rediculous there is no easy way to say "get the url of the previous tab" in QuteBrowser
the only solution I found is
:back -t ;; yank ;; tab-close
@Efi this runs outside of tabs sandboxing
tells the browser to, according to the tab navigation history, go back by one page, copy the url to the clipboard, then close that tab.
@LottieVixen tabs should be sanboxed from each other anyway
