Two days ago I accidentally erased a large portion of my browsing history. I need to restore it. I am on a mac using the latest version of firefox for os X 10.8.5

well here the user faced same problem. refer to this for the solution: https://support.mozilla.org/en-US/que.../1036657#answer-666126

Hope It solves your problem. Thanks

Yeah, saw that and tried it or else I wouldnt have posted. I found the profile folder everything in it is dated 2013 2011 or later its strange. Also, the Plies flie or whatever its called ( i dont recall now) does not exist.

If you use the Time Machine then try to restore the file(s) from that backup.

You would need places.sqlite for the history and bookmarks.

As I replied yesterday, this did not work. places.sqlite does not exist.
