Restoring data

Hi there,

I had some problems with my bookmarks not syncing across my computers. On my main computers I decided to sign out of my chrome browser and sign back in - completely unaware that this would wipe my entire tabsoutliner history!!!!!!!!!!! SO now my bookmarks are syncing - I have now lost all my tabs "pulls hair out*.

Surely there is a way I can restore the tabs data. I have restored data from iPhones and computers before, quite long after it is deleted, so I am going to remain hopeful.

Any suggestions are appreciated.
