Show the issue. Did you try Firefox in Safe Mode? What security software are your running?

No security softwares or safe-mode. It was running off a sd card that I use for storage for my low-end pc and I had just tried reinserting it after a problem with a different app.

Data corruption maybe on my end………??????

Issue resolved? If so, mark this as resolved.
