Yesterday, I had Firefox open and running perfectly fine, and I had forgotten to shut down my laptop before closing it. Today, when I reopened my laptop, the Firefox window that was open instantly closed. I tried opening Firefox again, but it kept opening and closing immediately. It would show that there was an open window of it, but the window itself wouldn't open. It would run in the background but never actually open. I tried uninstalling and reinstalling, but it still did the same thing. Does anyone know a solution to this?
