Been browsing for three years and using firefox sync for as long as it's been around. Did the stupid thing and let CCleaner run without ring-fencing firefox and now my local history is gone. I was just wondering if it was at all possible to recover a previously saved version of my browsing history from my firefox sync, since it says that it saves it and seems to have previous versions of my bookmarks? I've tried a whole bunch of local options, I'm really just looking to see if Firefox Sync can help at all. Thanks.
