After the latest auto update all of my history, tabs/windows, and bookmarks were deleted and I can't recover them. I have tried importing bookmarks and it does not allow me to upload an old data file and I can't restore my previous session. I tried checking both profiles but neither had my information saved and now when I open the about:profiles says "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

I'm scared to try anything else because I don't want to mess anything up further but I really need my tabs and history back.

I restarted my computer and then reopened firefox and it had updated and I noticed my bookmarks were gone but my windows/tabs were open, so I tried to choose a file on the bookmark backup and nothing was happening so I restarted and after that all my history and tabs were gone and I couldn't restore them.

Hello!

Please take a look at the profile and bookmark data. If those still in your local files there might be a way to restore them. Please confirm if you have the files.

Storage Locations by Operating System Windows: Firefox profile data is stored in two separate locations : Main profile (bookmarks, passwords, settings): C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile_folder>\ Cache and temporary files: C:\Users\<username>\AppData\Local\Mozilla\Firefox\Profiles\<profile_folder>\ macOS: Profile data is located at ~/Library/Application Support/Firefox/Profiles/<profile_folder>/ Linux: Profile data is stored at ~/.mozilla/firefox/<profile_folder>/

Once you've identify that there is data to restore you can see Restore bookmarks, passwords, and data from an old Firefox profile

I don't see any files for Firefox anywhere in my system at that location. Is there anywhere else I can check on macOS? Or if it's been deleted, is there any way to recover the profile file?
