I have a(n embarrassingly) large number of windows and tabs open in Safari on Mavericks right now, which I'd like to save, and I'd also like to do an OS upgrade sometime this week.
I have "restore windows" turned on, and Safari re-opened them for me a couple of weeks ago when my Mac crashed and rebooted.
Can I be confident that the same will happen after installing El Capitan? If not automatically, is there a cache file or folder I can save before the install/dig up afterwards to restore the windows? Should I just bookmark all the tabs?
