Firefox history gone after downgrade
I had been using firefox 52 ESR for a while, but a few days ago I switched to 56 and used it till today before I decided to go back to ESR 52 and upon doing so all my browsing history is now gone. My bookmarks are fine, and all my saved passwords, extensions, and pretty much everything else is intact its just my history is gone. I tried the place.sqlite.corrupt trick in my profiles folder but there was no corrupt file there. I've switched back to 56, even tried going to Quantum and nothing worked. Please help I'd really like to get my history back as theres about a years worth of sites I've visited that I haven't bookmarked or saved.

Firefox may have created a new places.sqlite when it noticed that you downgraded the profile folder from a newer and incompatible Firefox version.
You should always be cautious when you downgrade and create a backup. There is no recover from lost history apart from restoring an older copy of places.sqlite.
You can check in Windows Explorer if there is a previous version of the file available.
- right-click: Properties -> Previous Versions

I tried that and thankfully the most recent restore point was a little over a week ago, so while I've lost my last week's worth of history but I'll gladly take that over close to a year's worth of history lost. Thank you thank you so much!!!
You're welcome
