Yesterday I installed an update to Firefox on my Samsung Galaxy S8 (running Android 9) that wiped out ~60 tabs and all my bookmarks and browsing history. Some of these bookmarks were from years ago and I'd like to recover the Firefox session files if possible, even just extracting the data to my PC through some means. I believe the Firefox session file is not yet deleted but is inaccessible through my phone because I don't have root access.

I found another post regarding this topic that mentions the Firefox session file is located in "/data/org.mozilla.firefox/files/mozilla/<profile>/sessionstore.bak", but that is on a rooted phone. I looked in the "Android/data/org.mozilla.firefox/files/" folder with the built-in file manager but there's only two folders inside - "Download" and "temp," both of which are seemingly empty. I also checked the above folder using the file browser in SmartSwitch while my phone was connected with the USB and the results were the same.

Is there any way to gain access to the hidden Firefox session file on a non-rooted Android phone? Or is there any software I can run on my PC to extract a root level image of the phone so I can dig through the Firefox data folder?

I have a phone backup via SmartSwitch from a few months ago but I don't think it contains the Firefox session data.
