My Firefox bookmarks disappeared because I accidentally created a profile

I’ve been using Firefox for months without manually creating a profile (I assume one is created by default). I had a lot of bookmarks, and today I accidentally created a profile manually, but then deleted it after noticing it didn’t have my bookmarks. Now, even after deleting it, I still don’t have my bookmarks, and Firefox keeps creating profiles for me. I checked backup files, but I can’t find anything, or maybe I don’t even know which folder I’m supposed to look in. My browsing history is gone, and I think I also lost my saved passwords or usernames for websites I used. I’ve already tried using firefox.exe -P and checking %appdata%\Mozilla\Firefox\Profiles\, but my bookmarks aren’t in either of those folders (.default or .default-release). Honestly, I really don’t want to believe I could have lost everything that easily. I even used Recuva to try recovering files like places.sqlite and checked the bookmarks folders in the only two directories where those files existed, but it was pointless. Honestly, I still don’t even understand how everything got deleted just from manually creating a profile. I really didn’t expect something like this to happen.
