Is it possible to recover my ols firefox session after deleting my Windoes 10 user folder?

Hello everyone, I'm trying to recover the tabs I had open in my old Firefox installation on Windows 10. I had accumulated many tabs that I wanted to keep, and I'd really appreciate some technical advice before giving up on recovering them. Here is my situation: My previous setup - I used Firefox on Windows 10, which was installed on a 500 GB SSD. - I believe I was signed in to my Mozilla account, although I'm not completely certain. - I had many tabs open that I would like to recover. What happened - I moved to a new Windows 11 installation on a separate 2 TB SSD. - I deleted the old Windows 10 `Users` folder on the 500 GB SSD. - Afterward, I ran a full H2testw write/read test on the 500 GB SSD. - I installed Firefox on Windows 11 and initially used it without signing in. What I've tried - I located Firefox session files, including `previous.jsonlz4` and `recovery.baklz4`, but used History Scrounger to determine that they belong to my new Windows 11 Firefox installation. - I have since signed in to my Mozilla account and can see browsing history from before the Windows 11 upgrade. - My current Firefox Sync settings show that synchronisation is enabled and that Open Tabs and History are included. - I also have Linux Mint installed on the 2 TB SSD, but I only started using Firefox on Linux Mint after setting up Windows 11. My questions: 1. Is there any way to retrieve the old Windows 10 session or its open tabs from my Mozilla account or Firefox Sync, even if the original Windows profile has been deleted? 2. Does the presence of old browsing history in my Mozilla account indicate that any additional session data might still be available? 3. Are there any other places where Firefox session data might have been preserved? 4. Given that I ran a full H2testw test on the old SSD, is there anything else worth checking before concluding that local recovery is no longer possible? I understand that browsing history and a saved session are different things. My main goal is to recover the actual collection of tabs that was open in my old Windows 10 installation, rather than simply reconstructing it from browsing history. I'd appreciate any suggestions for further investigation. Thank you!
