Desktop history deleted after Sync with iPad

more options

I synced my old iPad with the Firefox Account I use on my desktop on the 14th of this month, and for some reason it deleted everything in my history up to the 10th. Ironically now I have the history of my iPad from like 2017 in my desktop tho. How do I fix this? Is there any way to recover my old desktop history? I use it quite often as a resource.

Also how could something like this happen? Isn't the idea of Sync to merge?

I tried that 'index.dat' method but I have a million index.dat files and none of them are related to Firefox. Also it sounds fishy af.

It is possible that there has been a problem with places.sqlite (bookmarks and history) and that a new database has been created. In such a case the bookmarks are rebuilt from a JSON backup in the bookmarkbackups folder, but there is no backup of the history.

You can check if you have a places.sqlite.corrupt in the profile folder and possibly try to rename this file to replace the new places.sqlite. Make sure to keep a backup copy of the current places.sqlite.

If you can't use this then only an older backup of places.sqlite might restore the lost history.

You can look at a utility to browse System Restore points.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

I actually looked into places.sqlite with the notepad and, even though its mostly gibberish (obviously) I did find that websites are actually stored in plaintext, and it would appear as if my history was there intact.

I searched for some of those adresses my history/bookmarks inside Firefox and they don't show up, but I do remember having visited many of those. So the information is still there, only for some reason Firefox isn't reading it.

I don't have a .corrupt but I do have places.sqlite-shm and *.sqlite-wal.

Oh and I don't have system restore active ):
