> https://addons.mozilla.org/en-US/firefox/addon/tile-tabs-we/ https://addons.mozilla.org/en-US/firefox/addon/tile-tabs-we/ I already tried this extension - it basically opens new windows and tiles them side by side instead of splitting the current window. It is better than nothing but not really what I'm talking about. > You can also Ctrl+click all the tabs you want to save, like the pinned ones in the main window, right click on one of them, select Bookmark tabs, and save them in a bookmark folder. Then if you accidentally close them you can middle click that bookmark folder to reopen all of them at once. That describes my current workaround.
