Hello, I have macOS 10.12.3 with Safari 10.0.3 (12602.4.8) instaled. Everytime when I turn off my computer and start it again, all iCloud tabs are gone and bookmars or history from another devices are not synced.
I have In iCloud settings turned on Safari, but when im turn it off and set to on again, everything works well. But when I turn on my computer next time, I must do it again.
iMac (27-inch, Late 2012), OS X Mountain Lion (10.8.3)

After performing Step "1. Delete Caches and test.", my iCloud tabs from all my other devices were visible again in macOS Sierra (10.12.3 (16D32)) Safari (Version 10.0.3 (12602.4.8)) when I re-launched Safari.
1. go System Preferences - Icloud - uncheck Safari
2. restart mac
3. go System Preferences - Icloud - check Safari
worked on mine
to be exact, my problem was that suddenly, my Macbook Air Safari could not see all the tabs in all of my devices when i click the double square on the upper right hand corner of Safari. That double box opens up all open tabs across all devices. i tried the above steps and instantly, all the tabs were accessible again on my MBA.
An article : Set up and use iCloud Tabs - Apple Support
Sign out and sign back into iCloud on your Mac.
There was also a bug that if you had iCloud Drive turned off for Safari, your tabs wouldn't sync.
Thanks. This fixed mine as well.
