Where did my profile go? Where is my session?
I opened Firefox and it opened as usual... but I can't restore my session. not only that, my addons are all gone, my history is gone, everything is gone?!
How can this happen? Why would it happen without any messages? After I was using the Extended Support version and it upgraded to Quantum automatically and decided to purge my profile of addon data, making me lose all my old sessions and thousands of saved web pages, I'm absolutely losing my mind over the incredible data loss that Firefox is causing without thinking twice about it!?
I looked in %APPDATA%\Mozilla\Firefox\Profiles\ and there's only one folder in there and it has been created twenty minutes ago, when I started the browser. This is horrendous data loss if my previous profile is really gone!

Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.

If you were using Firefox ESR, then it should have updated via the ESR updater. Not the normal (Quantum) updater.
