Firefox on launch

So Firefox keeps removing all my pinned and old tabs every time I turn my PC off and on. It was good and working before a few days ago where the browser just reset all the tabs and went to the default tab with no pinned tabs and I couldn't "Restore previous session".

Update. I noticed that when I turn the PC on and open Firefox the app opens but it doesn't pop up as a window. It closes the window but on Task Manager says its on. So when I try to relaunch it opens a separate window with no pinned tabs nor the ability to restore previous session either.
