Hey guys, I was using an older version of firefox 52.0.1 and accidentally pressed update to the newer version. I installed the older version 52.0.1 back from the directory. But when I did that I lost my tabs, my bookmarks, and my browsing history. Unable to restore my tabs, I decided to try to restore my bookmarks. I read somewhere to delete all the places.sqlite in the profile folder and then firefox would start up with the most recent bookmarks in the bookmarks backup folder. So I deleted the places.sqlite including the ones that had a dash (-) behind them. Not realizing that it would delete my browsing history which had no backup folder like the bookmarks do. So I was able to get my bookmarks, but not the browser history. Is all my browser history lost? Or is there still a way to get it back? Please help.
