Hello. I had a old version of fire fox. Yesterday I updated to new. Also down loaded other apps recommended. One clear question. I have the new fire fox tab for browsing. I also have the original still on my phone. The square box that reps the app. Do I delete it. There are all kinds of bugs this new system found. Deleting and diverting all passwords. I need a recommendation on what to do. Also all night it told me more bugs. Now I’m the phone says it has a virus. Damaged infected. ???
