Sessions
Sessions is an extension for managing your Safari browsing history.
The internet is a big place with lots of interesting corners. It can be difficult to find the time to consume the steady flow of new information as quickly as it is produced and found. If you've ever found yourself after several days of browsing with dozens of open tabs in Safari that you really do mean to get around to, but which you have difficulty balancing against the competing pressures of keeping up to date, Sessions is here to help.
Sessions keeps track of your open windows and tabs for you, with automatic periodic backups for easy and robust session restoration across launches. If the current panoply of tabs gets to be too much for either you or Safari, simply save a snapshot of the session at any time and start fresh, secure in the knowledge that you can go back and revisit all of those links in their associated context at your future leisure.
