Save your tabs and load anytimeLoad your tabs back from where you left!
You have sets of bookmarks each having a name that you would like. Reload those any time you want.
Say you are working on a python project and referring to a bunch of websites. You can save these "open tabs" as bookmarks as a set with a name a name of your choice say for python project you might name it "my py project". Whenever you feel like working on that project just load those bookmarks and that's it! You are back !
Do try it out and don't forget to rate it! Thanks!
