Save History tabs/groups

Maybe I am missing something but is there a way to save a group of tabs as a folder within bookmarks? Or is there a way to save the historical tab groups (previous groups of tabs that you can restore within history) as folders so that I can start with a fresh browser but easily look back? I spend too much time trying to save and organise open web pages. This would be much easier, save a lot of time and help with performance issues. No doubt I will end up with multiple historical browser tab folders but this would be better than having to deal with the performance issues of having 100s of open tabs and inevitably losing some from time to time. Thanks.
