My places.sqlite file has places.sqlite.corrupt just under it in my second profile's folder. I tried renaming the corrupt file as just places.sqlite (calling the first places.sqlite something else) and restarting as suggested but the history still won't show up, and when I check the folder, places.sqlite is once again places.sqlite.corrupt (with a places.sqlite file just above it.)

Is there a way to somehow get Quantum to read my old history?
