I'm not really a browser tab hoarder, nor a tabcloseophobic (fear of closing tabs?) ;). However, I keep a bunch of them pinned. Since I mostly work on smaller screens, it would be nice of #firefox could stack/group tabs, to free up some tab space (stack, as in , click the stack/group tab, and u get a popup with a list of the tabs). Vivaldi has something close to this ...(not that I'm switching).
