I've seen all the questions about restoring previous sessions. I am not trying to restore tabs from a previous sessions although I have in the past and the advice on this forum has been great. I am trying, essentially, to archive a session. I do a lot of research on various topics and it is not uncommon to have many tabs open. Right now there are over 300 tabs open on my desktop. Is there an add on or plugin/app that would allow me to name and archive a session so that I could start a new session while retaining a past session for access later?

Thank you!
