The tabs are open but not loaded so yeah, it's like a bookmark. Once you click the tab it loads the content.

  I thought you needed an extension to unload tabs?

    Just quit firefox and restore tabs on restart, all of the tabs are now unloaded but still present in the tab bar.

    about:processes can kill processes, which will unload their tabs.
