Hi @Deleted, I am sure that you are aware of the "Continue where you left off" option in the Start Up settings. You can also use Ctrl+Shift+D to save all open tabs to a specific folder in Favorites, and then later Righ-Click and select Open All (##). Lastly you can install one of the several extensions that save off specific tabs. Other than these options, we don't have a way to do this right now. In the current version of Microsoft Edge we have Tab Sweep which allows you to save of specific tabs for later use, but we have not transferred that feature over to the next version of our browser yet. If these options are insufficient, what are you looking for and can you describe your scenario in more detail so that we can try and understand the whole problem?
